Bis[2-(hy­droxy­imino)­cyclo­hexan-1-one oximato-κ²N,N′]copper(II)

In the title compound, [Cu(C₆H₉N₂O₂)₂], the Cu^II atom is located on an inversion center and has a square-planar environment. Two 2-(hy­droxy­imino)­cyclo­hexan-1-one oxim­ate monoanions chelate to the Cu^II 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.
