N-Benzylidene-5(3)-methylpyrazole-3(5)-carbohydrazide schiff base (BMPCH) has been synthesised and its complexes with Co(II), Ni(II) and Cu(II) have been prepared.The solid metal complexes have been characterised by various physicochemical techniques.Magnetic and electronic spectral data indicate that the bis-complexes, M(BMPCH)2X2*nH2O are grossly octahedral except the halocomplexes of cobalt(II) which may be considered as mixtures of octahedral and tetrahedral species in the light of available data.The IR spectra indicate that in the bis-derivatives, the ligand exhibits neutral tridentate (NON) behaviour coordinating through the tertiary nitrogen of the pyrazole ring, the ketonic oxygen and the azomethine nitrogen of the hydrazide component.The counterions (X) are ionic in character.
