Abstract

The ligand 2,6-bis-(salicylaldehydehydrazone)-4-chlorophenol (H5L) and its binuclear lanthanide(III) nitrate complexes {[Ln2(H4L)3(NO3)](NO3)2.mH2O} where Ln = La, Ce, Pr, Nd, Sm, Gd, Dy, Er, Yb and Y, have been synthesized. The complexes were characterized by chemical analysis, conductance, magnetic moment measurements and infrared spectra. Infrared study indicates that the ligand behaves both as neutral and ionic O donors and as neutral N donors.
