Thermal, spectral and magnetic studies on glycine complexes of cobalt(II), nickel(II) and zinc(II) with hydrazine
摘要:
Hydrazinium metal glycinates [(N2H5)(2)M(NH2CH2COO)(4)] and bis(hydrazine)metal glycinates, [M(NH2CH2COO)(2)(N2H4)(2)], where M = Co, Ni or Zn have been prepared and characterized by chemical analyses, magnetic moments and vibrational and electronic spectra. The thermal behaviour of these compounds has been studied by thermogravimetry and differential thermal analyses. These complexes decompose with high exothermicity giving metal powder as the final residue. The X-ray powder data of each set of complexes show isomorphism among themselves.
