Abstract : Metal chloride and metal sulphate complexes of fumaric acid dihydrazide (FZ) of the tupe M X/sup 2/. FZ.H/sup 2/O, [M=Cu(II),Ni(II), and X=C/sup 2/ and 1/2 SO/sup 4/ and NiX/sup 2. FZ.2H/sup 2/O have been prepared. Coordination errors though oxygen of the > C=0 and nitrogen of the -NH/sup 2/ of the hydrazide group. A polymeric octahedral structure for MC/sup 2/ complexes and sulphate bridged quadricoordinate structure for MSO/sup 4/ complexes has been proposed. TGA and DTA results are also reported.
