Poly[aqua-bis(μ-benzene-1,2-dicarboxyl-ato)ethano-ltetra-lithium].

In the crystal structure of the title compound Li(4)(C(8)H(4)O(4))(2)(C(2)H(5)OH)(H(2)O), there are four crystallographically independent metal centers each of which is coordinated by four O atoms. The benzene-1,2-dicarboxyl-ate groups act as bidentate-bridging ligands producing a two-dimensional coordination network parallel to the ab plane. The coordination polymer is further stabilized by coordination of water and ethanol mol-ecules by the Li(+) ions. Simultaneously, the water and ethanol mol-ecules are involved in O-H⋯O and C-H⋯π inter-actions.
