Bis-hydrazine metal o-nitrobenzoate, [M(o-NO 2 C 6 H 4 COO) 2 (N 2 H 4) 2 ], where M= Co, Ni, Zn or Cd have been prepared by mixing aqueous solution of respective metal nitrate hydrate with aqueous solution containing o-nitrobenzoic acid and hydrazine hydrate in 2:4 ratio. These complexes were analysed by chemical and CHN analyses. The IR spectrum of these complexes reveals the monodentate nature of carboxylate ions and bridged bidentate nature of hydrazine. Thermal behaviour of these complexesfatcat:gxeptdus5bfijkyajrjs5kba2u
