Bis[μ-2-(4-hydroxyphenyl)acetato]-κ3O,O′:O;κ3O:O,O′-bis{aqua(4,4′-bipyridine-κN)bis[2-(4-hydroxyphenyl)acetato-κ2O,O′]dysprosium(III)} monohydrate

In the title dinuclear complex, [Dy2(C8H7O3)6(C10H8N2)2(H2O)2]·H2O, the DyIII atoms are coordinated by eight O atoms from four 2-(4-hydroxyphenyl)acetate (HPAA) ligands and a water molecule, and one N atom from a 4,4′-bipyridine (bipy) ligand in a distorted tricapped trigonal prismatic geometry. Whereas four HPAA ligands coordinate to just two DyIII atoms, the remaining two ligands bridge the two DyIII atoms. In the crystal, O—H...O and O—H...N hydrogen bonds link the molecules into a three-dimensional network.
