Poly[[[bis­(acetato-κO)copper(II)]-μ-1,4-diimidazol-1-ylbenzene-κ(2) N (3):N (3′)] dihydrate]

In the title linear coordination polymer, {[Cu(C(2)H(3)O(2))(2)(C(12)H(10)N(4))]·2H(2)O}(n), the Cu(II) atom is coordinated by two N atoms from two different symmetry-related 1,4-diimidazol-1-ylbenzene (dib) ligands and two carboxyl­ate O atoms from two acetate ligands in a square-planar geometry. The Cu atoms are linked by the dib ligands, forming an extended chain. These chains are linked by O—H⋯O hydrogen bonds into a three-dimensional supra­molecular network. The Cu(II) atom lies on a center of inversion.
