Abstract
The title copper coordination polymer, [Cu3(C8H4O4)2(C8H5O4)2(C10H8N2)2]n, was synthesized by reacting Cu(NO3)2, isophthalic acid and 1,10-phenanthroline under hydrothermal conditions. The trinuclear unit presents a central almost planar CuO4 chromophore with the cation on a symmetry center, and two symmetry-related CuN2O3 groups with the metal centre in a distorted square-pyramidal environment. These units are bridged by isophthalate ligands into one-dimensional double-chain coordination polymers which are, in turn, connected by various π–π stacking interactions (face-to-face distance ca 3.45 Å) and O—H⋯O hydrogen bonds, forming a three-dimensional supramolecular network.
