Synthesis,characterization and antibacterial investigation of divalent metal complexes of NO-donor ligand: {5-chloro-2-[(4-chlorobenzylidene)-amino]phenyl}(phenyl)methanone

A ligand l has been synthesized by the condensation of 4-chlorobenzaldehyde and 2-amino-5-chlorobenzophenone. the complexes 1-5 of pb+2,ni+2,co+2,cu+2 and cd+2 with ligand were prepared. the newly synthesized ligand l and its complexes 1-5 were characterized on the basis of elemental analyses,molar conductance,1h nmr,ir and ms spectral data. the ligand was also characterized by x-ray crystallography. by electronic spectra and magnetic moment data,the square planar geometry for complex 1 and the octahedral geometry for complexes 2-5 were proposed. the conductivity data suggests non-electrolytic nature of the complexes 1-5. the complexes have higher antibacterial activity than the parent ligand l. © 2012.
