The crystals belong to the orthorhombic space group C222, with a = 9.226, b = 12.092, c = 16.513 Å, Z = 4. A single crystal X-ray diffraction analysis has shown that the title compound, in which all carbon atoms are sp2 hybridized, exists with the ten membered ring in a slightly twisted tub conformation. The 13C nmr spectrum is also reported.

The title compound, C10H20N6 (2), was prepared from N,N´,N´´-triaminoguanidinium chloride. Solvent- and temperature-dependent 1H NMR spectra indicating prototropic tautomerism were observed in solution. The crystal and molecular structure was determined by X-ray diffraction analysis. The compound crystallizes in the hexagonal space group P63/m. The molecules lie on crystallographic mirror planes parallel to the a,b plane, which are separated from each other by 3:37 Å . The threefold crystallographic symmetry of the molecules is due to disorder with positional averaging of individual molecules.
