title: Bis[μ-2-(4-hy-droxy-phen-yl)acetato]-κO,O':O;κO:O,O'-bis-{aqua-(4,4'-bipyridine-κN)[2-(4-hy-droxy-phen-yl)acetato-κO,O']samarium(III)} monohydrate.
abstract: The dinuclear title complex, [Sm(2)(C(8)H(7)O(3))(6)(C(10)H(8)N(2))(2)(H(2)O)(2)]·H(2)O, contains two Sm(III) atoms, six deprotonated p-hy-droxy-phenyl-acetic acid (PAA) mol-ecules, two 4,4'-bipyridine (bipy) mol-ecules, two coordinated water mol-ecules and one solvent water molecule. Each Sm(III)ion is nine-coordinated by seven O atoms from four PAA ligands, one water O atom and one N atom from a bipy ligand in a distorted geometry. The PAA ligands are coordinated to the Sm(III) ion in bridging and bridging tridentate modes. The asymmetric unit also contains one uncoordinated water mol-ecule. The occurrence of numerous O-H⋯O and O-H⋯N hydrogen bonds involving coordinated and non-coordinated water mol-ecules builds up an intricate three-dimensional network.
