Refined crystal structure of tetra-µ-acetato-bisaquodicopper( II )

The structure of the title compound has been refined from three-dimensional X-ray diffractometer data. Crystals are monoclinic, space group C2/c, with Z= 4 in a unit-cell of dimensions: a= 13·168(2), b= 8·564(2), c= 13·858(2)Å, and β= 117·02(1)°, Full-matrix least-squares refinement, using 1280 independent reflections, has reached R 0·047.The refinement has, as expected, confirmed the original two-dimensional structure determination and much more accurate bond lengths and bond angles have been obtained: mean Cu–O(acetate) 1·969 Å, Cu–O(water) 2·156, and Cu ⋯ Cu is 2·616 Å. The geometry of the acetate bridges is planar and bond lengths and angles are as expected.
