Resumo

The Cu atom of the title compound, [Cu(C4H7N2O3)2], is in a tetragonally distorted octahedral environment. A carboxyl O atom and the α-amino N atom from each ligand coordinate to Cu in a trans square-planar configuration [Cu—O = 2.003 (3) and 2.020 (3) Å, and Cu—N = 2.029 (4) and 2.049 (4) Å]. The octahedron is completed by bridging amide O atoms from adjacent molecules [Cu—O = 2.229 (4) Å and Cu—O = 2.885 (4) Å] separated by c translations. This arrangement creates infinite chains linked in the [001] direction, stabilized by intra- and intermolecular N—H...O bonds. The structure has already been published [Stephens, Vagg & Williams (1975). Acta Cryst. B31, 841–845]; this redetermination reports the structure with higher precision.
