Synthesis and characterization of two Ni(II) complexes with furfural s-methylthiosemicarbazone

Abstract

Synthesis of two Ni(II) complexes with furfural S-methylthiosemicarbazone (HL) of the formula [Ni(HL)2(H2O)2](ClO4)2 (A) and [Ni(HL)2(ClO4)2] (B) are reported. Compound A was obtained from an ethanolic solution of Ni(ClO4)2·6H2O and HL, whilst compound B was produced by heating compound A to 378 K. An X-ray analysis of the complex A showed that it has a trans(H2O)-trans(HL) octahedral configuration in which HL behaves as a bidentate (NN) ligand. On the basis of the IR and electronic spectra as well as the magnetism, it was found that the compound B has also an octahedral configuration in which, HL and ClO4 groups, are coordinated. © 1983.
