Synthesis, characterization and X-ray crystal structures of the bis?ligand zinc(II) and cadmium(II) complexes of the methylpyruvate Schiff base of S-methyldithiocarbazate
Abstract:New bis-chelated Zn II and Cd II complexes of empirical formula, [M(mpsme) 2 ] (mpsme ¼ the anionic form of the tridentate ONS donor ligand formed from methylpyruvate and S-methyldithiocarbazate) have been prepared and characterized by conductance, i.r., electronic and n.m.r. spectroscopic techniques. Spectral evidence supports a sixcoordinate distorted octahedral structure for these complexes. X-ray crystallographic structural analysis also confirms that, in both the [Zn(mpsme) 2 ] and [Cd(mpsme) 2 ] complexe… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
