It has been found that the Schiff base behaves as a neutral tridentate SNO ligand forming chelates with I : 2 or I : I (metal: ligand) stoichiometry. The complexes of Co(II), Ni(II), and Zn(II) are proposed to have an octahedral structure, while the Cu(II) complex is suggested to have a square-pyramidal geometry. All of the complexes show nonelectrolytic behavior.eninfo:eu-repo/semantics/closedAccessSynthesisSalicylaldehyde Schiff BaseBinuclear ComplexesPyrimidine-2-ThioneArticle
