Synthesis and structural characterization of lanthanide picrate complexes with a new binaphthylamide

Abstract

Solid complexes of lanthanide picrates with N-Ethyl-2-{2′-[(ethyl-phenyl-carbamoyl)-methoxy]-[1,1′]binaphthalenyl-2-yloxy}- N-phenyl-acetamide (L), [Ln(pic) 3L] (Ln=La, Tb, Y), have been prepared and characterized by elemental analysis, IR and 1H NMR spectra. The molecular structure of [Tb(pic) 3L] shows that the Tb(III) ion is nine-coordinated by four oxygen atoms from the L and five from two bidentate and one unidentate picrates. The complex forms a 1D supramolecular structure along z-axis.
