Coordination preferences of NNO and NNS Schiff base ligands with Co(III) complexes / Ispitivanje koordinacionih sposobnosti NNO i NNS Šifovih baza kao liganada u kompleksima Co(III)
(Belgrade : Serbian Chemical Society, 2022)
Two Co(III) complexes [Co(L1)2]BF4·H2O (1) and [Co(L2)(N3)3] (2) with condensation product of thiosemicarbazide and 2-acetylthiazole (HL1) and the condensation product of 2-acetylpyridine and Girard’s P reagent (HL2Cl) ...
Crystallographic investigation of the iron phosphate tungsten bronze (Fe-PWB)
(Institut za multidisciplinarna istraživanja, 2023)
In this paper, 12-tungstenphosphoric acid (PWA) was synthesized in combination with FeCl3 at room temperature (25 oC). At such manner, Fe3+ ion exchange gave new 12-tungstenphosphoric salt of the transition metal iron ...
Synthesis of new praseodymium doped phosphate tungsten bronze
(Belgrade : Serbian Chemical SocietyBelgrade : Serbian Young Chemists’ Club, 2022)
For the preparation of praseodymium doped phosphate tungsten bronze (Pr-PWB), as a
starting material is used 12-tungstophosphoric heteropoly acid H3PW12O40×29H2O
