Tetra-μ-acetato-κ8O:O′-bis[(3-hydroxypyridine-κN)copper(II)]

In the title dimeric complex, [Cu-2(Ac)(4)(3-PyOH)(2)] or [Cu-2(C2H3O2)(4)(C5H5NO)(2)] (Ac- is acetate and PyOH is hydroxypyridine), each Cu-II atom exists in a square pyramidal coordination environment, defined by four different acetate O atoms and one 3-hydroxypyridine N atom. Two CuII atoms are bridged by four acetate groups, and the center of the dimer corresponds to a crystallographic center of symmetry, the Cu...Cu separation being 2.6598 (8) Angstrom. These dimeric units are linked via O-H...O hydrogen bonds into a two-dimensional layer supramolecular network.
