Poly[[μ-aqua-diaquabis(μ-furan-2,5-dicarboxylato-κ2O2:O5)bis(1,10-phenanthroline-κ2N,N′)dicopper(II)] N,N-dimethylformamide monosolvate]

Abstract

The asymmetric unit of the title compound, {[Cu2(C6H2O5)2(C12H8N2)2(H2O)3]·C3H7NO}n, contains two CuII 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 CuII 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—Owater distances, which are 2.415 (2) and 2.639 (2) Å for one CuII atom and 2.3560 (19) and 2.911 (4) Å for the other. Ligands L and one independent water molecule bridge the CuII atoms, forming corrugated polymeric layers parallel to the ab plane. Intermolecular O—H...O and C—H...O hydrogen bonds consolidate the crystal packing.
