There are two crystallographically independent mol-ecules in the asymmetric unit of the title compound, C(22)H(17)BrN(6). The dihedral angles between the imidazo[4,5-b]pyridine mean plane and the phenyl rings are 20.4 (2) and 24.0 (2)° in the two mol-ecules. The orientation of triazoles compared to the imidazo[4,5-b]pyridine system is almost the same in both mol-ecules, with dihedral angles of 64.2 (2) and 65.1 (2)°. However, the main difference between the two mol-ecules lies in the arrangement of the phenyl groups compared to imidazo[4,5-b]pyridine in each mol-ecule. Indeed, in the first mol-ecule the dihedral angle between the plane of the phenyl ring and that of the imidazo[4,5-b]pyridine system is 67.7 (2)°, while in the second mol-ecule the plane of the phenyl ring is almost perpendicular to that of the imidazo[4,5-b]pyridine system with a dihedral angle of 86.0 (2)°.
在标题化合物C(22)H(17)BrN(6)的不对称单元中存在两个晶体学独立分子。在这两个分子中，咪唑并[4,5 - b]吡啶平均平面与苯环之间的二面角分别为20.4 (2)°和24.0 (2)°。与咪唑并[4,5 - b]吡啶体系相比，三唑的取向在两个分子中几乎相同，二面角分别为64.2 (2)°和65.1 (2)°。然而，两个分子之间的主要差异在于每个分子中苯基相对于咪唑并[4,5 - b]吡啶的排列方式。实际上，在第一个分子中，苯环平面与咪唑并[4,5 - b]吡啶体系平面之间的二面角为67.7 (2)°，而在第二个分子中，苯环平面几乎垂直于咪唑并[4,5 - b]吡啶体系平面，二面角为86.0 (2)°。
