Bis[-2-(4-hydroxyphenyl)acetato]-³O,O':O;³O:O,O'-bis{aqua(4,4'-bipyridine-N)bis[2-(4-hydroxyphenyl)acetato-²O,O']gadolinium(III)} monohydrate

Abstract: In the dinuclear title complex, [Gd₂(C₈H₇O₃)₆(C₁₀H₈N₂)₂(H₂O)₂]·H₂O, the two Gd^III 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 Gd^III 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.
