Abstract
The structure of the title compound, C8H16N4, which consists of four fused seven-membered rings, has been redetermined at 173 K. This redetermination corrects the orientation of two H atoms, which were located at unrealistic positions in the original room-temperature study [Murray-Rust (1974 ▶). J. Chem. Soc. Perkin Trans. 2, pp. 1136–1141]. The complete molecule is generated by -42m symmetry, with one quarter of a molecule [one N atom (site symmetry m), two C atoms (one with site symmetry m and the other with site symmetry 2) and two H atoms] in the asymmetric unit. No directional interactions beyond van der Waals contacts are apparent in the crystal structure.

R factor = 0.050; wR factor = 0.141; data-to-parameter ratio = 14.7. The structure of the title compound, C8H16N4, which consists of four fused seven-membered rings, has been redetermined at. This redetermination corrects the orientation of two H atoms, which were located at unrealistic positions in the original room-temperature study [Murray-Rust (1974). No directional interactions beyond van der Waals contacts are apparent in the crystal structure.
