1,2-dinitroguanidine.

The title compound, CH(3)N(5)O(4), is almost planar, and the conformation is fixed by two intramolecular N-H...O hydrogen bonds. Owing to the delocalization of pi-electron density over the whole molecule, there is through-conjugation, with the C-N, N-N and N-O bond lengths having values intermediate between those typical for the corresponding single and double bonds.

2-nitrimino-1-nitroimidazolidine.

The molecule of the title compound, C(3)H(5)N(5)O(4), has a planar geometry. Due to the presence of a second nitro group, the lengths of the two conjugated C--N bonds are different. Nevertheless, the conjugation of the nitrimine group spreads to the nitramine group. Intermolecular N--H...O bonds connect molecules into dimers in the crystal structure.
