Abstract
The title complex was crystallized from a diethylene glycol (DEG) solu tion containing 0.2 M neodymium trichloride hexahydrate. The X-ray str uctural analysis of the complex showed that [Nd(DEG)(3)](3+) cation co nsists of a central neodymium atom coordinated with nine oxygen atoms from the three DEG ligands with the approximate tricapped-trigonal pri smatic configuration. There was a slight difference in conformation am ong the three DEG chains: one DEG ligand exhibited a zig-zag chain, wh ile 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- an ions surrounding the [Nd(DEG)(3)](3+) cation. (C) 1997 Elsevier Scienc e S.A.
