Some high coordination compounds of lanthanides(III) derived from N-isonicotinamidosalicyaldimine

Ram K. Agarwal, Himanshu Agarwal


A new series of lanthanide(III) nitrates, isothiocyanates and perchlorates coordination complexes of N-isonicotinamidosalicyaldimine (INH-SAL) with the general composition LnX3.n(INH-SAL) (Ln = La, Pr, Nd, Sm, Gd, Tb or Dy; X = NO3-, n = 2; X = NCS-, n = 2 or 3 and X = ClO4-, n = 4) have been reported. All the complexes were characterized by chemical analyses, conductance, molar weight, magnetic moment measurements, infrared and electronic spectra. IR spectra indicate that the ligand behaves as a neutral N,O-donors. Thermal properties of the complexes have also been studied.
