CRYSTAL STRUCTURE OF (1R,5S)-9-NITRO- 1,2,3,4,5,6-HEXAHYDRO-1,5-METHANOPYRIDO[1,2-a][1,5] DIAZOCIN-8-ONE (9-NITROCYTISINE), C11H13O3N3

The title compound (1, trivial name: 9 (or 3)-nitrocytisine) crystallizes with two independent molecules in the asymmetric unit. In its structure two rings form a bispidine framework that is fused to a 3-nitro-2-pyridone group. The half-normal probability plot reveals that the two molecules do not show any significant geometrical differences, except in conformations of the nitro-group, which is involved in intermolecular interactions. The crystal packing structure of the title compound is described in terms of three-dimensional supramolecular arrays built up from chains of N-H-O (nitro-group), hydrogen bonds and weak intermolecular C- H … O=C interactions, with graph-set descriptors C²2(6) and C²2(JQ) motifs, which together result in R(4)4(26) rings motifs. These chains are additionally stabilized by intermolecular NO2…π interactions.
