Bis(μ-cyclo-hexane-1,3-dicarboxyl-ato)-κO:O,O;κO,O:O-bis-[aqua-(1,10-phenanthroline-κN,N')zinc(II)]

The cyclo-hexane-1,3-dicarboxyl-ate dianion in the dinuclear centrosymmetric title compound, [Zn(2)(C(8)H(10)O(4))(2)(C(12)H(8)N(2))(2)(H(2)O)(2)], has a chair conformation with both carboxyl-ate groups in equatorial positions. One carboxyl-ate group chelates a Zn(II) atom, whereas the other binds through one O atom only to confer a six-coordinate status to the N-heterocycle-chelated water-coordinated Zn(II) atom. Adjacent dinuclear mol-ecules are linked by O-H⋯O hydrogen bonds into a linear chain.
