Synthesis, Magneto-Spectral and Biological Studies of Manganese(II) Complexes with Heteroaroyl Hydrazones

Abstract

Manganese(II) complexes of benzoic acid [(furan-2-yl)methylene]hydrazide, benzoic acid [1-(furan-2-yl)ethylidene]hydrazide, benzoic acid [(thiophen-2-yl)methylene]hydrazide and benzoic acid [1-(thiophen-2-yl)ethylidene]hydrazide have been synthesized and characterized by elemental analysis, conductivity, magnetic susceptibility, electronic and infrared spectral data. Magnetic and electronic data suggest dimeric tetrahedral with benzoic acid [(furan-2-yl)methylene]hydrazide, benzoic acid [(thiophen-2-yl)-methylene]hydrazide and dodecahedral with benzoic acid [1-furan-2-yl)ethylidene]hydrazide and benzoic acid [1-(thiophen-2-yl)-ethylidene]hydrazide ligands. All the ligands and complexes have been screened for their antifungal and antibacterial activity against fungi and bacteria.
