AB  - Ten 5-(substituted phenylazo)-3-cyano-1-ethyl-6-hydroxy-4-methyl-2-pyridones were studied (five new compounds) to provide insight into the electronic effects of diverse substituents located at different positions in their phenyl moieties. The structural features of these dyes were examined by combining experimental and theoretical approaches. The crystal structures of two derivatives were revealed by X-ray crystallography and diverse packing modes owing to different intermolecular interactions (- stacking and lone pair- interactions, as well as hydrogen bonds) were found. A study on lattice energy and energy related to the molecular pairs obtained from their crystal packing was performed. The tautomerism and ionisation of the dyes in ethanol or N,N -dimethylformamide solution were rationalised in terms of diazo component substitution pattern.

AB  - A series of cycloalkane-5-spirohydantoins bearing a halogeno substituted benzyl group (X = Cl and Br) in position 3 has been synthesized and their structures (1-6) have been determined by a single crystal X-ray diffraction method. These compounds have multiple functional groups, which allow greater competition and/ or cooperation among the different intermolecular interactions in the formation of their crystal structures. The molecules are linked together by paired N-H... O hydrogen bonds in R22(8) rings, while the CH. O interactions lead to their further association into double chains. The contribution of the cycloalkyl ring depends on its conformational flexibility and the multiple C-H donor implications. In the case of compounds 1-4 bearing the cyclopentyl or the cyclohexyl ring, halogen bonding (X...O) interactions give rise to a supramolecular pseudo-hexagonal network. In addition, the C-H... X interactions with a higher degree of multifurcation at the halogen acceptor have an important role in the formation of the crystal structure. Regarding compounds 5 and 6 with the cycloheptane ring, the X. O interaction is absent, and along with the C-H. X interactions, these compounds realize an alternative crystal structure with an emphasis on the X. p interactions. The lattice energies of all these crystal structures, as well as the intermolecular pair energies, have been calculated using PIXEL and further partitioned into coulombic, dispersive, polarization and repulsive factors. The crystal structures have also been subjected to Hirshfeld surface analysis which reveals that approximately 75% of the close contacts correspond to relatively weak interactions. The application of both concepts has provided a new insight into the relationship between the molecular interactions and crystal structures of the hydantoin derivatives.

AB  - In this work, a combined experimental and theoretical study on the structures of methoxy substituted 5-phenylazo-3-cyano-1-ethyl-6-hydroxy-4-methyl-2-pyridones has been reported. The dyes under the investigation have been thoroughly characterized. X-ray single-crystal analysis shows that 5-(4-methoxyphenylazo)-3-cyano-1-ethyl-6-hydroxy-4-methyl-2-pyridone crystallizes in the hydrazone form. Quantum chemical calculations of energies, geometrical structure and vibrational wavenumbers of the investigated dyes have been performed using density functional theory. The optimized geometrical parameters obtained by density functional theory calculations are in good conformity with the single-crystal data. The fundamental vibrational wavenumbers, as well as their intensities have been calculated and a good agreement between observed and scaled calculated wavenumbers has been achieved. Stability of the molecule arising from hyperconjugative interactions and charge delocalization has been analyzed using natural bond orbital analysis. Vibrational, nuclear magnetic resonance and natural bond orbital analysis confirm that the prepared dyes exist in the hydrazone tautomeric form in the solid state and dimethyl sulfoxide solution.

AB  - Two new series of hydantoin derivatives, 3-(4-substituted benzyl)-5,5-diphenyl- and 3-(4-substituted benzyl)-5-ethyl-5-phenylhydantoins, were synthesized and their antiproliferative activity was tested against human colon cancer HCT-116 and breast cancer MDA-MB-231 cell lines. The presence of different substituents on both hydantoin and benzyl moieties changed the antiproliferative activity of the investigated hydantoins, whereby most of the compounds showed superior antiproliferative activity against MDA-MB-231 than against the HCT-116 cell line. The structure of three compounds was studied by single-crystal X-ray diffraction. The general structural characteristic is the presence of N-H center dot center dot center dot O hydrogen bonds in crystal packings. The molecular geometry and bonding features of the investigated hydantoins in the ground states were calculated using the density functional method. The relationship between structure and antiproliferative activity was discussed. The data presented in this investigation afford guidelines for the preparation of new hydantoin derivatives with greater antiproliferative activity.

AB  - Carbon-supported Pt and Pt-Rh-Sn catalysts were synthesized by the microwave-polyol method in ethylene glycol solution and were investigated in the ethanol electro-oxidation reaction. The catalysts were characterized in terms of structure, morphology and composition employing the X-ray diffraction (XRD), scanning tunneling microscopy and energy-dispersive X-ray spectroscopy techniques. The STM analysis indicated rather uniform particles and particle sizes below 2 nm for both catalysts. The XRD analysis of the Pt/C catalyst revealed two phases, one with the main characteristic peaks of the face-centered cubic crystal structure (fcc) of platinum and the other related to the graphite-like structure of the carbon support, Vulcan XC-72R. However, in the XRD pattern of the Pt-Rh-Sn/C catalyst, diffraction peaks for Pt, Rh or Sn could not be resolved, indicating extremely low crystallinity. The small particle sizes and homogeneous size distributions of both catalysts could be attributed to the advantages of the microwave-assisted modified polyol process in ethylene glycol solution. The Pt-Rh-Sn/C catalyst was highly active for ethanol oxidation with the onset potential shifted by more than 150 mV to more negative values and with currents nearly 5 times higher in comparison to the Pt/C catalyst. The stability tests of the catalysts, as studied by chronoamperometric experiments, revealed that the Pt-Rh-Sn/C catalyst was evidently less poisoned than the Pt/C catalyst. The increased activity of Pt-Rh-Sn/C in comparison to Pt/C catalyst was most probably promoted by the bi-functional mechanism and the electronic effect of the alloyed metals.
AB  - Pt i Pt-Rh-Sn katalizatori na ugljeniku razvijene površine su sintetizovani poliol-mikrotalasnim postupkom u rastvoru etilenglikola i ispitivani za reakciju eletrohemijske oksidacije etanola u kiseloj sredini. Katalizatori su okarakterisani strukturno, morfološki i po sastavu korišćenjem XRD, STM i EDX tehnika. STM analiza je potvrdila da su Pt i Pt-Rh-Sn čestice uniformne veličine i prečnika manjeg od 2 nm. XRD analiza Pt/C katalizatora pokazala je prisustvo dve faze, jedne sa glavnim karakterističnim pikovima za pljosno-centriranu kubnu kristalnu strukturu platine (111, 200, 220 i 311) i druge sa difrakcionim pikom na 2q oko 25° karakterističnim za heksagonalnu strukturu vulkana XC-72R (ugljeničnog nosača). XRD analiza Pt-Rh-Sn/C katalizatora nije pokazala karakteristične pikove, što je indikacija veoma male kristaličnosti katalizatora. Aktivnost katalizatora ispitivana je potenciodinamičkim i hronoamperometrijskim merenjima. Pt-Rh-Sn/C katalizator je veoma aktivan za oksidaciju etanola sa početkom reakcije na potencijalima za oko 150 mV pomerenim ka negativnijim vrednostima i strujama koje su oko pet puta veće u poređenju sa Pt/C katalizatorom. Stabilnost katalizatora ispitivana hronoamperometrijski pokazala je da se Pt-Rh-Sn/C katalizator manje truje od Pt/C katalizatora. Mala veličina i homogena distribucija čestica mogu se pripisati prednostima mikrotalasne sinteze i modifikovanog poliol postupka u rastvoru etilenglikola. Veća aktivnost Pt-Rh-Sn/C katalizatora u poređenju sa Pt/C katalizatorom posledica je bi-funkcionalnog mehanizma i elektronskog (ligand) efekta metala u sintetizovanoj leguri.

AB  - The morphology of perovskite LaNiO3 (LNO) thin films is a very important feature considering the fact that they could be used as an electrode material in ferroelectric devices. In this work, LNO films were prepared from citrate precursors. The films were deposited on Si (100) and Pt covered Si substrates [Pt (111)/Ti/SiO2/Si] Using the spin-on technique. The phase composition of the films was confirmed by X-ray powder diffraction analysis, while the microstructures were investigated by atomic force microscopy. The influence of the metal ion:citric acid:ethylene glycol ratio on the morphology of the films was investigated. After optimization of these parameters, very homogenous, uniform and crack-free LNO films were obtained.
