title: Tetra-mu-acetato-kappa2O:O'-bis[(4-phenylpyridine-kappaN)copper(II)].
abstract: The title compound, [Cu(2)(C(2)H(3)O(2))(4)(C(11)H(9)N)(2)] or [Cu(2)(MeCO(2))(4)(phpy)(2)] (phpy is 4-phenylpyridine), consists of centrosymmetric dimers in which the CuII atoms display a square-pyramidal CuO(4)N coordination, with four acetate O atoms in the basal plane [Cu-O 1.975 (3)-1.987 (3) A] and the phpy N atom in the apical position [Cu-N 2.150 (3) A]. The Cu atoms are 2.654 (1) A apart and are bridged by four acetate groups. The discrete dimers are extended into a three-dimensional supramolecular array through intermolecular pi-pi-stacking interactions.
