3,5-bis[(N,N-dimethylamino)methyl-eneamino]-1-methyl-4-nitropyrazole from X-ray powder diffraction data

The structure of the title compound, C10H17N7O2, was determined using a bon d-restrained Rietveld refinement which gave bond lengths and angles within the expected ranges. Although the two nearly planar (N,N-dimethylamino)meth yleneamino groups are inclined at approximately 46 degrees to the pyrazole ring, the conformations of the two amino chains are different, owing to eit her a repulsion effect of the pyrazole-methyl group or a short interatomic contact with the nitro group in one of the chains.
