Complexation behaviour of the Schiff base ligand, 1-phenyl-2,3-dimethyl-4-(benzylamino)pyrazole-5-one with manganese metal ion has been studied. The Schiff base ligand, 1-phenyl-2,3-dimethyl-4-(benzylamino)pyrazol-5-one was synthesized by the condensation reaction of 4-aminoantipyrine and benzaldehyde. The ligand and complex were characterized based on their colour, melting point, solubility, infrared and mass spectral analyses. Spectroscopic analyses suggested the involvement of C=N, C=O and chloride ions in chelation. A tetrahedral geometry was suggested for the manganese complex.
