The synthesis, magnetic and spectral studies of mixed-ligand complexes of nickel(II) derived from chelating 4-oximino-2-pyrazoline-5-one derivatives, viz., 4-benzoytoxime-3-methyl-1-phenyl-2-pyrazoline-5-one (bomppH), 4-acetyloxime-3-methyl-1-phenyl-2-pyrazoline-5-one (aomppH) and 3-methyl-1-phenyl-4-propionyloxime-2-pyrazoline-5-one (mppopH), and certain heterocyclic ligands, viz., 3-methyl-1-phenyl-2-pyrazoline-5-one (mpp), 4-amino-2,3-dimethyl-1-phenyl-3-pyrazoline-5-one (adpp), 2,3-dimethyl-1-phenyl-3-pyrazoline-5-one (dpp), 2,3-dimethyl-4-methylaminomethanesulfonate sodium-1-phenyl-3-pyrazoline-5-one (dmspp), benzimidazole (bzl) and benzothiazole (bzt) are described. The complexes, which have been characterized by conductance measurements, electron spin resonance, magnetic measurements, thermogravimetric analyses, electronic and infrared spectral studies have the general formulas [Ni(A-A)2(L)2] and [Ni(A-A)2(L-L)] where, (A-A)H = bomppH, aomppH, or mppopH, L = mpp, dpp, bzl or bzt and L - L = adpp or dmspp. All the complexes were found to be non-electrolytes and octahedral structures have been proposed for them.
