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.

Geometry. All e.s.d.'s (except the e.s.d. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell e.s.d.'s are taken into account individually in the estimation of e.s.d.'s in distances, angles and torsion angles; correlations between e.s.d.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell e.s.d.'s is used for estimating e.s.d.'s involving l.s. planes.

Refinement. Refinement of F2 against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F2, conventional R-factors R are based on F, with F set to zero for negative F2. The threshold expression of F2 > σ(F2) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F2 are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger.
