Poly[[(μ3-5,6-dicarboxybicyclo[2.2.2]oct-7-ene-2,3-dicarboxylato)(1,10-phenanthroline)copper(II)] monohydrate]

Abstract

In the title compound, {[Cu(C12H10O8)(C12H8N2)]·H2O}n, the CuII ion is five-coordinated by two N atoms from one phenanthroline ligand and three O atoms from three different H2L2− anions (H4L is bicyclo[2.2.2]oct-7-ene-2,3,5,6-tetracarboxylic acid) in a distorted square-pyramidal geometry. Each H2L2− ion bridges three CuII atoms to form a zigzag sheet parallel to the ab plane. The crystal structure is consolidated by O—H...O hydrogen bonds.
