Description
Summary:The dinuclear title complex, [Sm2(C8H7O3)6(C10H8N2)2(H2O)2]·H2O, contains two SmIII atoms, six deprotonated p-hydroxyphenylacetic acid (PAA) molecules, two 4,4′-bipyridine (bipy) molecules, two coordinated water molecules and one solvent water molecule. Each SmIIIion 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 SmIII ion in bridging and bridging tridentate modes. The asymmetric unit also contains one uncoordinated water molecule. The occurrence of numerous O—H...O and O—H...N hydrogen bonds involving coordinated and non-coordinated water molecules builds up an intricate three-dimensional network.
