title: Catena-poly[[(1,10-phenanthroline-kappa(2)N,N')copper(II)]-micro-(dihydrogen benzene-1,2,4,5-tetracarboxylato)-kappa(2)O(1):O(4)].
abstract: In the title compound, [Cu(C(10)H(4)O(8))(C(12)H(8)N(2))](n), the Cu(II) cation has a four-coordination environment completed by two N atoms from one 1,10-phenanthroline (phen) ligand and two O atoms belonging to two dihydrogen benzene-1,2,4,5-tetracarboxylate anions (H(2)TCB(2-)). There is a twofold axis passing through the Cu(II) cation and the centre of the phen ligand. The [Cu(phen)](2+) moieties are bridged by H(2)TCB(2-) anions to form an infinite one-dimensional coordination polymer with a zigzag chain structure along the c axis. A double-chain structure is formed by hydrogen bonds between adjacent zigzag chains. Furthermore, there are pi-pi stacking interactions between the phen ligands, with an average distance of 3.64 A, resulting in a two-dimensional network structure.
