Aqua­(2,2′-bipyridine-κ(2) N,N′)(3,5-dinitro­benzoato-κO (1))copper(II) tetra­hydro­furan monosolvate

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 penta­coordinate Cu(II) atom bound by two monodentate carboxyl­ate ligands, a bidentate 2,2′-bipyridine mol­ecule [dihedral angle between pyridine rings = 5.0 (2)°] and a water mol­ecule. The resulting N(2)O(3) donor set defines a distorted square-pyramidal geometry with the coordinated water mol­ecule in the apical position. In the crystal, the presence of O—H(w)⋯O(c) (w = water and c = carbon­yl) hydrogen bonding leads to the formation of a supra­molecular 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 mol­ecules, which are disordered over two orientations in a 0.678 (11):0.322 (11) ratio, occupy voids defined by the complex mol­ecules and are held in place via C—H⋯O inter­actions.
