Abstract: In the dinuclear title complex, [Gd2(C8H7O3)6(C10H8N2)2(H2O)2]·H2O, the two GdIII ions are nine-coordinated by seven O atoms from four deprotonated p-hydroxyphenylacetic acid (PAA) ligands, one water O atom and an N atom from a 4,4'-bypyridine (bipy) ligand in a distorted tricapped trigonal-prismatic geometry. The deprotonated PAA ligands are coordinated to the GdIII atom either as chelating on the same metal or in a tridentate bridging mode. Numerous O-HO and O-HN hydrogen bonds involving hydroxyl, coordinated and uncoordinated water molecules build up an intricate three-dimensional network.
