Synthesis, Characterization, X-Ray Crystal Structures and Antibacterial Activity of Zinc(II) and Vanadium(V) Complexes Derived from 5-Bromo-2-((2-(methylamino)ethylimino)methyl)phenol

Abstract

Three new zinc(II) and one vanadium(V) complexes, [Zn₂Cl₂L₂] (1), [Zn₂I₂L₂] (2), [ZnCl₂(HL)] (3), and [V₂O₂(μ-O)₂L₂] (4), where L is 5-bromo-2-((2-(methylamino)ethylimino)methyl)phenolate, have been synthesized and characterized by elemental analyses, IR and UV-Vis spectra, as well as molar conductivity. Structures of the complexes were confirmed by single crystal X-ray diffraction. Complexes 1 and 2 are isostructural dinuclear zinc compounds, with the Zn atoms in square pyramidal coordination. The Zn atoms in the mononuclear complex 3 are in tetrahedral coordination. Complex 4 is a dinuclear vanadium(V) compound, with the V atoms in octahedral coordination. The complexes were assayed for antibacterial activities by MTT method.
