Abstract: In the title compound, [Cu(C6H9N2O2)2], the CuII atom is located on an inversion center and has a square-planar environment. Two 2-(hydroxyimino)cyclohexan-1-one oximate monoanions chelate to the CuII atom and the Cu-N distances are 1.920 (3) and 1.930 (3) Å. There are two short intramolecular O-H...O hydrogen bonds between the ligands. The complex molecules stack into columns extended along the c axis, with a Cu...Cu distance between adjacent molecules of 3.3060 (3) Å.
