Abstract:In the title dimeric complex, [Cu2(Ac)4(3-PyOH)2] or [Cu2(C2H3O2)4(C5H5NO)2] (Ac− is acetate and PyOH is hydroxypyridine), each CuII 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) Å. These dimeric units are linked via O—H…O hydrogen bonds into a two-dimensional layer supramolecular network.
