Abstract
A series of lanthanide(III) complexes of the compositions M(HL)3 (M=La, Pr, Nd, Sm, Dy and Y; H2L = 2- thenoyltrifluoroacetone isonicotinoyl hydazone) and M(HL)L (M = Er and Yb) have been synthesized and characterized by elemental analyses, conductance measurements, IR, 1H NMR and electral data and thermal analyses. The ligand can coordinate as mono- and di-anions.
