Syntheses, Characterization, and Antibacterial Property of Polynuclear Cobalt(III) and Copper(II) Complexes Derived from Similar Tridentate Schiff Bases

Abstract

An end-on azido-bridged trinuclear cobalt(III) complex [Co₃(L¹)₂(μ_1,1-N₃)₄(N₃)₂(OMe)(MeOH)] (I) and a phenolato-bridged dinuclear copper(II) complex [Cu₂(L²)₂(NCS)₂] (II), where L¹ is the deprotonated form of 2-((2-(dimethylamino)ethylimino)methyl)-4-fluorophenol, and L² is the deprotonated form of 2-((3-(dimethylamino)propylimino)methyl)-4-fluorophenol, have been prepared and characterized by elemental analyses, IR and UV-Vis spectra, and single crystal X-ray diffraction (CIF files CCDC nos. 1023376 (I); 1023377 (II)). The Co atoms in complex I are in octahedral coordination, and the Cu atoms in complex II are in square pyramidal coordination. The antibacterial properties have been tested on some bacteria and yeast.
