ABSTRACT: The cyclo-hexane ring in the title compound, C(21)H(24)N(8), adopts a chair conformation and the five-membered heterocyclic ring to which it is fused adopts a twist conformation on their common C-C bond. The substituents on the N atoms of the central five-membered heterocycle are arranged trans with respect to the central ring. The terminal benzotriazole rings are oriented at angles of 74.66?(8) and 84.18?(8)° with respect to the mean plane of the central heterocycle. The angle between the two benzotriazole rings is 30.80?(9)°. The bond lengths and angles are within normal ranges; the largest deviation from expecta-tion is for a long N-CH(2) bond length [1.476?(2)?Å] as a consequence of an anomeric effect. In the crystal, mol-ecules are connected by C-H?N hydrogen bonds.
