Abstract
Trivalent Lanthanides behave as hard acid and thus are expected to form stronger stable complexes with ligands having N-donor atoms. Coordination number less than six are uncommon for the lanthanides. Substituted Pyrazolones have been reported to posses’ strong pharmaceutical properties.
Complexes were prepared by adding 40 ml hot ethanolic solution of ligand (3M mol) to ethanolic solution of lanthanide (III) isothiocyanate (1M mol). Molar conduction, molecular weight, magnetic susceptibility, infrared and electronic spectroscopy were used to characterization of newly synthesized complexes
