【Abstract】 A new Schiff base ligand has been prepared by condensation of 4 [N,N Bispropylamino] benzaldehyde and benzyl dithiocarbazate by molecular design. Its neutral bisligand chelates, ML 2[M= Ni(Ⅱ), Cu(Ⅱ)] were also prepared and characterized by IR, MS,UV, melting point and molel conductivity. The ligand is deprotonated to give the thiol tautomer, coordinationed to metal ions via the thiolato sulpur and β nitrogen upon stable neutral complexes formation.更多还原
