Bis(μ-2-phenyl-acetato-κO:O)bis-[(2,2'-bipyridyl-κN,N')(2-phenyl-acetato-κO)copper(II)] dihydrate.

The mol-ecule of the binuclear title complex, [Cu(2)(C(8)H(7)O(2))(4)(C(10)H(8)N(2))(2)]·2H(2)O, is located on an inversion centre. The Cu atoms are bridged by two O atoms of the monodentate phenyl-acetate groups [Cu-O = 1.9808 (14) and 2.3668 (14) Å]. The longer of the two bridging Cu-O bonds takes the apical position of the distorted square-pyramidal environment of the Cu atom, which is completed by two N atoms of the chelate 2,2'-bipyridine ligand [Cu-N = 2.0107 (17) and 2.0234 (16) Å]. The mol-ecules are assembled into stacks along [100] through π-π inter-actions with inter-planar distances of 3.630 (4) and 3.407 (3) Å; the resulting stacks are further connected into a three-dimensional supra-molecular architecture by O-H⋯O and C-H⋯O hydrogen-bonding inter-actions.
