TY - JOUR A1 - Rivera, Augusto A1 - Ríos-Motta, Jaime A1 - Bolte, Michael T1 - Redetermination of 1,3,6,8-tetra­aza­tri­cyclo­[4.4.1.13,8]dodeca­ne T2 - Acta crystallographica. Section E, Structure reports online N2 - 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[Murray-Rust, P. (1974). J. Chem. Soc. Perkin Trans. 2, pp. 1136-1141.]). 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.
