Poly[[bis(μ2-6-methylpyrazin-2-carboxylato-κ3N1,O:N4)copper(II)] dihydrate]

Abstract

In the title compound, {[Cu(C6H5N2O2)2]·2H2O}n, the CuII ion (site symmetry overline{1}) is coordinated by two N,O-bidentate ligands and two N-monodentate ligands in a distorted CuO2N4 octahedral geometry. Each anion acts as a bridge between two cations, thus forming a two-dimensional polymeric network parallel to the ab plane. The packing is consolidated by O—H...O hydrogen bonds. One of the O atoms of the ligand and both water molecules are disordered.
