catena-Poly[[aqua­bis­(N (6)-benzyl­adenine-κN (3))copper(II)]-μ-benzene-1,4-dicarboxyl­ato-κ(2) O (1):O (4)]

In the title compound, [Cu(C(8)H(4)O(4))(C(12)H(11)N(5))(2)(H(2)O)](n), the Cu(II) ion is five-coordinated by two carboxyl­ate O atoms from two symmetry-related benzene-1,4-dicarboxyl­ate ligands, two N atoms from two symmetry-related N (6)-benzyl­adenine ligands and one water O atom in a square-pyramidal environment. The Cu(II) and water O atoms lie on a twofold rotation axis, and the benzene-1,4-dicarboxyl­ate ligand lies on an inversion center. The water O atom occupies the apical position and the basal plane is occupied by two O atoms and two N atoms. Each benzene-1,4-dicarboxyl­ate anion acts as a bis-monodentate ligand that binds two Cu(II) cations, forming an infinite chain extending parallel to [001]. The N (6)-benzyl­adenine ligands are attached on both sides of the chain. Neighboring chains are further inter­connected into the resulting three-dimensional supra­molecular architecture via O—H⋯O, N—H⋯O and N—H⋯N hydrogen bonds.
