Abstract
The title complex, [Cu2(C4H4O5)2(H2O)]n, has a two-dimensional layer structure. The Cu atom has a distorted octahedral (CuO6) environment and is coordinated by four carboxylate group O atoms from three different oxydiacetate ligands in a planar arrangement and one half-occupancy water molecule and an ether O atom in the axial positions. In the crystal structure, weak intra- and intermolecular O—H⋯O hydrogen bonds help to stabilize the crystal packing. The structure has already been published [Whitlow & Davey (1975 ▶). J. Chem. Soc. Dalton. Trans. pp. 1228–1232]; this redetermination reports the structure with higher precision.
