title: Poly[[(μ-3,4-dicarboxy-tetra-hydro-furan-2,5-dicarboxyl-ato-κO,O,O:O)(1,10-phenanthroline-κN,N')copper(II)] 0.69-hydrate].
abstract: In the crystal structure of the title compound, {[Cu(C(8)H(6)O(9))(C(12)H(8)N(2))]·0.69H(2)O}(n), the Cu(II) atom has a distorted octa-hedral geometry, coordinated by four O atoms from two 3,4-dicarboxy-tetra-hydro-furan-2,5-dicarboxyl-ate ligands and two N atoms from one 1,10-phenanthroline ligand. One of the carboxylate groups bridges the Cu(II) atoms, forming a zigzag chain running along the b axis. The chains are linked by a π-π inter-action between aromatic rings with a centroid-to-centroid distance of 3.567 (1) Å, and by hydrogen bonds between the carboxyl-ate group and the disordered water mol-ecule, forming a three-dimensional network.
