  • Abstract

    A new series of hydrazine complexes of 3d transition metal 2,4 dichlorophenoxy acetates of the formula M(2,4 di-Cl PhOAc) 2(N2H4)2,where M = Mn, Co, Ni or Cd have been prepared and studied. The compositions of the complexes have been determined by chemical analyses. Infrared spectral data indicate the bidentate bridging by hydrazine molecules and unidentate coordination by carboxylate ions. Thermogravimetry and differential thermal analyses in air have been used to study the thermal behaviour of the complexes. The simultaneous TG-DTA traces of all the complexes show multi-step degradation and the final products are found to be the respective metals.
