Bis(N-nitroso-N-pentyl­hydroxy­laminato-κ²O,O′)copper(II)

In the centrosymmetric title compound, [Cu(C₅H₁₁N₂O₂)₂], the Cu²⁺ ion, located on an inversion centre (Wyckoff position 2b), is in a square-planar environment, surounded by four O atoms of the N—O groups of two N-nitroso-N-pentyl­hydroxy­laminate ligands [Cu—O = 1.9042 (17) and 1.9095 (16) Å]. The hy­droxy­laminate monoanions are bidentate chelating ligands. The Cu²⁺ cations form stacks along [010], with inter­molecular Cu...N contacts of 3.146 (2) and 3.653 (2) Å.
