Bis(μ-2-phenyl­acetato-κ(2) O:O)bis­[(2,2′-bipyridyl-κ(2) N,N′)(2-phenyl­acetato-κO)copper(II)] dihydrate

The mol­ecule 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 phenyl­acetate 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 mol­ecules are assembled into stacks along [100] through π–π inter­actions with inter­planar distances of 3.630 (4) and 3.407 (3) Å; the resulting stacks are further connected into a three-dimensional supra­molecular architecture by O—H⋯O and C—H⋯O hydrogen-bonding inter­actions.
