Synthesis And Characterization Of Rare Earth Metal Complexes Of 1'-Ethylferrocenylcarbonyl Hydrazine

Rare earth metal complexes of ferreocenylcarbonyl hydrazineLnL₃(ClO₄)₃·nH₂O(where Ln=La, Pr, Nd, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb, Lu;n=1-5)have been synthesized and characterized by elemental analyses, electricalconductance, IR and ¹HNMR spectra. The redox properties of ligand and some of itscomplexes have been investigated by cyclic voltammetric method. The solidfluorescence spectra of Sm(â…¢), Eu(â…¢), Th(â…¢), Dy(â…¢) complexes have also beenstudied.The ligand L(L=1'-ethylferrocenylcarbonyl Hydrazine)is bidentate, coordinatingthrough the amino N atom and the carbonyl O atom. The complexes are electrolytesof 1:1 style and one of perchlorate anions is outer sphere.
