The ligand N-(4'-butyrylidene-3-methyl-1-phenyl-2-pyrazolin-5-one)-p-anisidine was prepared and characterised by M.P., elemental analyses & spectral studies. The transition metal complexes of the ligand using Mn(III), Co(III), Ti(III), V III) Ru(III) VO(IV) and MoO(V)were prepared and characterised using elemental analyses, molar conductance, magnetic moments, electronic, i.e. and MNR spectral studies.
