Abstract
The monoclinic compound CuC4O4·2 H2O (space group P 21/c) was prepared from aqueous acetate buffered solution. The structure was solved from a twinned crystal. Chains consisting of squarate dianions and Cu2+ , which is coordinated octahedrally in a strongly distorted manner, are the main feature. Only two squarate oxygen atoms contribute considerably to the coordination of Cu2+. Neighbouring chains share common oxygen atoms (H2O . Osquarate) of the coordination polyhedra. Furthermore the chains are very probably interlinked by strong hydrogen bonds. Thermal decomposition of CuC4O4·2 H2O leads to CuO.Keywords
