A host of new Fe(II), Co(II), Ni(II), Ru(III), Rh(III), Ir(III), Cr(III), Pd(II), Cu(II) and Mn(II) complexes with benzilmonoximehydrazide-o-chlorobenzaldehyde (HBMHoCB) ligand have been prepared and characterised through physicochemical and analytical data. The electronic and magnetic moment data studies classify the reported as 5 or 6-membered coordinated geometry. The FT(IR) spectra scrutiny between the HBMHoCB ligand and its bivalent and trivalent metal complexes and in analogy with the crystal structure analysis indicate that the HBMHoCB ligand exercises neutral bidentate (N, N) behaviour through azomethine and oximino group bind with central bivalent as well as trivalent metal ions
