Synthesis,Characterization and X-Ray Structural Determination of the Nine-coordinate Tris-aqua Tetra-oxamato Neodymium(III) Complex [Nd(Hoxm) 3 (H 2 oxm)·2.5H 2 O] n †

Abstract

The reaction of Nd^III with oxamic acid yields [Nd(Hoxm)3(H₂oxm)·2.5H₂O]n 1 (H₂oxm = oxamic acid) which contains nine-coordinate Nd centres linked into chains via four-coordinate Hoxm^- ligands; the chains are connected via an array of H-bonds.
