Synthesis and structure of water-soluble complexes of copper fumarate and succinate with monoethanolamine

New water-soluble copper(II) complexes with dicarboxylic acids were obtained by the heterogeneous reaction of copper hydroxy carbonate with succinic or fumaric acid in water at 50°C. The additional introduction of monoethanolamine (MEA) into the complexes ensured high solubility of copper succinate and fumarate. The structures of the complexes [Cu(Suc) · 2MEA] · H2O and [Cu(Fum) · 2MEA] · H2O were studied by X-ray diffraction (CCDC nos. 2352578 and 2352579, respectively). The compounds were found to have a polymeric structure composed of zigzag chains.
