ABSTRACT:
Bis-hydrazine metal 3,5-dinitro benzoates [M(m-C6H3(NO2)2COO)2(N2H4)2] and bis-hydrazine 3,5-dinitro salicylates [M(m-C6H2(NO2)2(OH)COO)2(N2H4)2], where M= Mn, Co, Ni, Zn or Cd have been prepared and characterised by chemical analyses, spectral, thermal and X-ray powder diffraction studies. The infrared spectra of these complexes suggest the bridging bidentate nature of hydrazine moieties and monodentate nature of carboxylate ions. The TG-DTA analyses reveal that both the series of complexes undergo thermal degradations at much lower temperatures (180-430 oC) to yield respective metal oxides as the final residue. The X-ray powder data of each set of complexes show isomorphism within the series.
