Synthesis and Crystal Structure of CuC40 4*2 H20

چکیده
The monoclinic compound CuC40 4-2 H ;0 (space group P 2t/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 (H :0 . O squarate) of the coordination polyhedra. Furthermore the chains are very probably interlinked by strong hydrogen bonds. Thermal decomposition of CuC40 4-2 H20 leads to CuO.
