Diaquabis(quinoxaline-2-carboxylato-kappa2N1,O)copper(II).
In the title compound, [Cu(C9H5N2O2)2(H2O)2], the Cu(II) ion lies on an inversion centre and has an elongated centrosymmetric octahedral environment, equatorially trans-coordinated by two N,O-bidentate quinoxaline-2-carboxylate ligands and axially coordinated by two water O atoms. Symmetry-related molecules are linked by strong O-H...O hydrogen bonds, involving the uncoordinated carboxyl O atom of the carboxylate group and the coordinated water molecules, to form a two-dimensional network. Weak intermolecular C-H...N interactions also stabilize the crystal structure.
