    • Abstract


      Complexes of the type [M(N2H4)2(NCS)2], where M = Mn(II), Fe(II), Co(II), Ni(II), Zn(II), Cd(II) and Mg(II) have been prepared and characterized by chemical analysis. infrared and Mössbauer spectroscopy and magnetic moments. Hydrazine acts as a bridge between the two metal ions through the N-atom forming a distorted octahedral environment around the metal ion. Thermal decomposition of the complexes was studied in air and nitrogen atmosphere usingtg anddta techniques. The thermal stability of the complexes in nitrogen and the M-N stretching frequencies of M-NCS and M-N2H4 obey Irwing-Williams order for the bivalent metal complexesi. e. Mn2+<Fe2+<Co2+<Ni2+>Zn2+>Cd2+
