Tetra-kis[μ-2-(4-hy-droxy-phenyl)-acetato]-κO,O':O;κO:O,O'-bis-{aqua-(4,4'-bi-pyridine-κN)bis-[2-(4-hy-droxy-phenyl)-acetato-κO,O]neodymium(III)} monohydrate.

Abstract

The title complex, [Nd2(C8H7O3)6(C10H8N2)2(H2O)2]·H2O, contains two Nd atoms, six 4-hy­droxy­phenyl­acetate (hpaa) anions, two 4,4′-bipyridine mol­ecules (bipy) and two water mol­ecules; an additional water mol­ecule of solvation is also present in the crystal structure. Each of the NdIII ions is nine-coordinated by seven O atoms from four hpaa ligands, an N atom from a bipy ligand and an O atom from a water mol­ecule in a distorted tricapped trigonal-prismatic geometry. The hpaa ligands are coordinated to the NdIII ions in the bridging and bridging tridentate modes. Extensive O—H⋯O, O—H⋯N and C—H⋯O hydrogen bonding stabilizes the crystal structure.
