Abstract

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-(hy-droxy-imino)-cyclo-hexan-1-one oxim-ate 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 intra-molecular O-H⋯O hydrogen bonds between the ligands. The complex mol-ecules stack into columns extended along the c axis, with a Cu⋯Cu distance between adjacent mol-ecules of 3.3060 (3) Å.
