title: Aqua-(2,2'-bipyridine-κN,N')(3,5-dinitro-benzoato-κO)copper(II) tetra-hydro-furan monosolvate.
abstract: The title complex, [Cu(C(7)H(3)N(2)O(6))(2)(C(10)H(8)N(2))(H(2)O)]·C(4)H(8)O, features a penta-coordinate Cu(II) atom bound by two monodentate carboxyl-ate ligands, a bidentate 2,2'-bipyridine mol-ecule [dihedral angle between pyridine rings = 5.0 (2)°] and a water mol-ecule. The resulting N(2)O(3) donor set defines a distorted square-pyramidal geometry with the coordinated water mol-ecule in the apical position. In the crystal, the presence of O-H(w)⋯O(c) (w = water and c = carbon-yl) hydrogen bonding leads to the formation of a supra-molecular chain propagating along the c axis, which associates into a double chain via C-H⋯ O and π-π contacts between pyridyl rings [centroid-centroid distance = 3.527 (3) Å]. The solvent mol-ecules, which are disordered over two orientations in a 0.678 (11):0.322 (11) ratio, occupy voids defined by the complex mol-ecules and are held in place via C-H⋯O inter-actions.
