Lanthanidec (III) Complexes of 2-Thenoyl-Trifluoroacetone Isonicotinoyl Hydrazone

摘要

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.
