Cu(II), Mn(II) and Zn(II) complexes of hydrazones with quaternary ammonium moiety: Synthesis, characterization and DFT calculation

Abstract

The HLCl ligand with metal salts Cu(BF4)2‧6H2O / MnCl2‧4H2O / Zn(BF4)2‧6H2O and NaN3, in methanol form mononuclear penta-coordinated complexes [CuL(N3)(CH3OH)]BF4 (1) and [ZnL(N3)2] (2) and binuclear [Mn2L2(µ-1,1-N3)2(N3)2]⋅2CH3OH (3) complex. Complexes 1, 2 and 3 were characterized by elemental analysis, IR spectroscopy, single-crystal X-ray diffraction, and DFT calculations.

U reakciji liganda HLCl sa solima metala Cu(BF4)2‧6H2O / MnCl2‧4H2O / Zn(BF4)2‧6H2O i NaN3 u metanolu, dobijeni su mononuklearni kompleksi koordinacionog broja pet: [CuL(N3)(CH3OH)]BF4 (1) i [ZnL(N3)2] (2) i dinuklearni kompleks [Mn2L2(µ-1,1-N3)2(N3)2]⋅2CH3OH (3). Kompleksi 1, 2 i 3 okarakterisani su elementalnom analizom, IC spektroskopijom, rendgenskom stukturnom analizom i DFT proračunima.
