Polynuclear Complexes of Fumaric Acid Dihydrazide with Cu (II), Ni (II) and Co (II)

Abstract

Metal chloride and metal sulphate complexes of fumaric acid dihydrazide (FZ) of the type MX2.FZ.H2O, [M = Cu (II), Ni (II), and X = Cl2 and 1/2 SO4] and NiX2.FZ.2H2O have been prepared. Coordination occurs though oxygen of the> C = O and nitrogen of the -NH2 of the hydrazide group. A polymeric octahedral structure for MCI2 complexes and sulphate bridged quadricoordinate structure for MS04 complexes has been proposed. TGA and DTA results are also reported.
