Synthesis and crystal structures of a new non-cyclic ligand and its lanthanum(III) complex

Abstract

A new non-cyclic ligand, tris(4-carboxy-3-oxabutyl) amine (H 3L · HCl) and its lanthanum(III) complex have been prepared and their crystal structures determined. In the lanthanum(III) complex the metal ion is coordinated to one nitrogen atom, three ether oxygen atoms, three carboxy oxygen atoms of one ligand and two bridging carboxy atoms from adjacent ligands giving a coordination number of nine. The LaOCOLa′ bridges produce an infinite network of complex molecules.
