Rapid Communication: Completion of the Isomorphous Ln(trensal) Series

Abstract

The Ce^III, Pr^III, Nd^III, Gd^III and Yb^III complexes of the heptadentate ligand 2,2´,2´´-tris(salicylideneimino) triethylamine, H₃trensal (in its trianionic form), have been synthesized and characterized structurally by X-ray crystallography. These five [Ln(trensal)] structures complete a rare isomorphous and isostructural series of lanthanoid complexes in the trigonal P^–3c1 space group with a ≈ 13.1 and c ≈ 16.5 Å
