title: 1,5-Dimethyl-2-nitro-imino-1,3,5-tri-azinane.
abstract: The asymmetric unit of the title compound, C(5)H(11)N(5)O(2), contains two independent mol-ecules. The two triazine rings adopt envelope conformations. Intra-molecular C-H⋯N and N-H⋯O hydrogen bonds result in the formation of two five- and two six-membered rings which are nearly planar; in addition, they are also nearly coplanar. In the crystal structure, inter-molecular N-H⋯N, C-H⋯N and C-H⋯O hydrogen bonds link the mol-ecules.
