• Variable-temperature H-1 NMR Spectra
• Layered Crystal Structure

The title compound, C10H20N6 (2), was prepared from N,N',N ''-triaminoguanidinium chloride. Solvent- and temperature-dependent H-1 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 P6(3)/m. The molecules lie on crystallographic mirror planes parallel to the a,b plane, which are separated from each other by 3.37 angstrom. The threefold crystallographic symmetry of the molecules is due to disorder with positional averaging of individual molecules.
