Metal cinnamate monohydrazinates of the formula M(cin)2N2H4, where M= Co or Zn, nickel crotante monohydrazinate monohydrate Ni(crot)2N2H4.H2O, metal cinnamate and crotonate dihydrazinates M(cin)2(N2H4)2 Where M = Co, Ni, Zn or Cd , M(crot)2(N2H4)2 Where M = Co or Ni and cadmium crotante dihydrazinate monohydrate Cd(crot)2(N2H4)2.H2O have been prepared and characterized by spectral, thermal and X-ray diffraction studies. Electronic spectra indicate that the cobalt and nickel complexes are high-spin octahedral complexes. The IR data show that the binding of hydrazine and the unsaturated carboxylate anion to the metal ion is bidentate. TG-DTA studies show that metal complexes undergo decomposition through metal carboxylate intermediate to give respective metal oxide as the final product. Xray powder diffraction patterns of the complexes indicate isomorphism among them.
