Deskripsi
In the title compound, {[Cu(C6H2N2O4)(C3H7NO)]·H2O}n, the Cu(II) atom is coordinated by an N,O-bidentate pyrazine-2,3-dicarboxylate (pzdc) dianion, two O atoms from two other pzdc anions and one O atom from the dimethlyformamide ligand, forming a distorted square-pyramidal CuNO4 geometry. The polymeric character of the structure is established by the formation of layers parallel to (100) via bridging pzdc ligands. O—H...O hydrogen bonding between water molecules and uncoordinated carboxylate O atoms leads to additional stabilization of the structure.
