Bis(N-nitroso-N-pentylhydroxylaminato-κ2 O,O′)copper(II)

In the centrosymmetric title compound, [Cu(C5H 11N2O2)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.
