Poly[[μ-aqua-diaqua­bis­(μ-furan-2,5-dicarboxyl­ato-κ(2) O (2):O (5))bis­(1,10-phenanthroline-κ(2) N,N′)dicopper(II)] N,N-dimethyl­formamide monosolvate]

The asymmetric unit of the title compound, {[Cu(2)(C(6)H(2)O(5))(2)(C(12)H(8)N(2))(2)(H(2)O)(3)]·C(3)H(7)NO}(n), contains two Cu(II) atoms, two furan-2,5-dicarboxyl­ate (L) ligands, two 1,10-phenanthroline (phen) ligands, three coordinating water mol­ecules and one N,N-dimethyl­formamide solvent mol­ecule. Each Cu(II) atom is coordinated by two N atoms from one phen ligand, two O atoms from two L ligands and two water mol­ecules in a distorted octa­hedral geometry. The main difference between the environments of the two independent Cu atoms is in the Cu—O(water) distances, which are 2.415 (2) and 2.639 (2) Å for one Cu(II) atom and 2.3560 (19) and 2.911 (4) Å for the other. Ligands L and one independent water mol­ecule bridge the Cu(II) atoms, forming corrugated polymeric layers parallel to the ab plane. Inter­molecular O—H⋯O and C—H⋯O hydrogen bonds consolidate the crystal packing.
