Abstract

The title complex was crystallized from a diethylene glycol (DEG) solution containing 0.2 M neodymium trichloride hexahydrate. The X-ray structural analysis of the complex showed that [Nd(DEG) 3] 3+ cation consists of a central neodymium atom coordinated with nine oxygen atoms from the three DEG ligands with the approximate tricapped-trigonal prismatic configuration. There was a slight difference in conformation among the three DEG chains: one DEG ligand exhibited a zig-zag chain, while the other two were approximately planar due to disordering of the zig-zag conformations. The unequivalence of the conformation among the DEG ligands could be explained by an asymmetric arrangement of Cl − anions surrounding the [Nd(DEG) 3] 3+ cation.
