title: rac-1-(Furan-2-ylmeth-yl)-N-nitro-5-(oxolan-2-ylmeth-yl)-1,3,5-triazinan-2-imine.
abstract: In the title compound C(13)H(19)N(5)O(4), which belongs to the insecticidally active neonicotinoid group of compounds, the triazane ring exhibits a half-chair conformation. The large discrepancy between the two nitro O-N-N bond angles [116.1 (2) and 123.98 (19)°] may be attributed to intra-molecular N-H⋯O hydrogen bonding involving one of the nitro O atoms as the acceptor. The delocalization of the electrons extends as far as the nitro group, forming coplanar π-electron networks. In the crystal, inversion dimers lined by pairs of N-H⋯O hydrogen bonds occur.
