ABSTRACT
The title compound, C(3)H(6)N(4)O(2), exhibits partial disorder with the refined occupancy ratios of the two components being 0.582â
(5)0.418â
(5). In the major component, the nitroso groups have a relative syn spatial arrangement [O=Nâ¯N=O pseudo-torsion angle = 1.1â
(4)°], whereas the other component has an anti disposition [177.6â
(1)°]. The N-N=O moieties are almost coplanar with a dihedral angle of 5.3â
(3)°, while in the minor occupied set of atoms, this angle is 8 (1)°. In both components, the imidazolidine ring adopts a twisted conformation on the C-C bond and the crystal structure shows the strain of this ring according to the N-CH(2)-CH(2)-N torsion angles [25.9â
(5) and -23.8â
(7)°]. In the crystal, molecules are linked by weak C-Hâ¯O hydrogen bonds.
