Synthesis, crystal structure and biological activity of a cobalt(III) complex derived from 6,6’-(2-hydroxypropane-1,3-diyl)bis(azanediyl) bis(methylene)bis(2-bromo-4-chlorophenol)

Abstract

A new dinuclear cobalt(III) complex, 2[Co2L(HL)N3]·5H2O, derived from the reduced Schiff base 6,6’-(2-hydroxypropane-1,3-diyl)bis(azanediyl)bis(methylene)bis(2-bromo-4-chlorophenol) (H3L), was synthesized and characterized by infrared and electronic spectroscopy, and single-crystal X-ray diffraction techniques. The ligand was firstly synthesized and bound to the Co(III) center. The compound contains two dinuclear [Co2L(HL)N3] complex molecules and five water molecules of crystallization. The Co atoms in the complex are in octahedral coordination. The complex shows effective antimicrobial activity.
