Tetrakis[μ-2-(4-hydroxyphenyl)acetato]-κ3O,O′:O;κ3O:O,O′-bis{aqua(4,4′-bipyridine-κN)bis[2-(4-hydroxyphenyl)acetato-κ2O,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.
