Bis[?-2-(4-hydroxyphenyl)acetato]-?O,O':O;?O:O,O'-bis{aqua(4,4'-bi-pyri-dine-?N)bis[2-(4-hydroxyphenyl)acetato-?O,O']gadolinium(III)} monohydrate.

ABSTRACT: In the dinuclear title complex, [Gd(2)(C(8)H(7)O(3))(6)(C(10)H(8)N(2))(2)(H(2)O)(2)]·H(2)O, the two Gd(III) ions are nine-coordinated by seven O atoms from four deprotonated p-hy-droxy-phenyl-acetic 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-H?O and O-H?N hydrogen bonds involving hydroxyl, coordinated and uncoordinated water mol-ecules build up an intricate three-dimensional network.

Project description:In the title complex, [Cu(C(2)HCl(2)O(2))(2)(C(12)H(8)N(2))(H(2)O)], the Cu(II) ion has a distorted square-pyramidal coordination geometry. The equatorial positions are occupied by two N atoms from a 1,10-phenanthroline ligand [Cu-N = 1.994 (3) and 2.027 (3) Å] and two O atoms from dichloro-acetate ligands and a water mol-ecule [Cu-O = 1.971 (2) and 1.939 (2) Å]. One O atom from another dichloro-acetate ligand occupies the apical positon [Cu-O = 2.152 (3) Å]. Inter-molecular O-H⋯O hydrogen bonds link the mol-ecules into centrosymmetric dimers. The crystal packing also exhibits weak inter-molecular C-H⋯O hydrogen bonds, π-π inter-actions [centroid-centroid distance = 3.734 (2) Å] and short inter-molecular Cl⋯Cl contacts [3.306 (2) and 3.278 (2) Å].
