title: Tetra-μ-benzoato-κO:O'-bis-[(benzoic acid-κO)nickel(II)].
abstract: The title compound, [Ni(2)(C(7)H(5)O(2))(4)(C(7)H(6)O(2))(2)], is composed of two Ni(II) ions, four bridging benzoate anions and two η(1)-benzoic acid mol-ecules. The [Ni(2)(PhCOO)(4)] unit adopts a typical paddle-wheel conformation. The center between the two Ni(II) atoms represents a crystallographic center of inversion. In addition, each Ni(II) ion also coordinates to one O atom from a benzoic acid mol-ecule. The crystal packing is realised by inter-molecular hydrogen-bonding inter-actions and π-π stacking inter-actions, with a centroid-centroid distance of 3.921 (1) Å.
