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, [Dy-2(C8H7O3)(6)(C10H8N2)(2)-(H2O)(2)]center dot H2O, the Dy-III 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 Dy-III atoms, the remaining two ligands bridge the two Dy-III atoms. In the crystal, O-H center dot center dot center dot O and O-H center dot center dot center dot N hydrogen bonds link the molecules into a three-dimensional network.
