1,1'-[(2-Phenyl-2,3-dihydro-1H-benz-imidazole-1,3-di-yl)bis-(methyl-ene)]bis-(1H-benzotriazole).

The imidazole ring in the title compound, C(27)H(22)N(8), adopts a slight envelope conformation with the C atom carrying the phenyl ring being the flap atom. The phenyl ring is almost perpendicular to the mean plane of the imidazole ring [dihedral angle = 88.90†(7)°]. The (1H-benzotriazol-1-yl)methyl groups bound to the imidazole ring are positioned on the same side of the imidazole ring. The dihedral angle between these benzotriazolyl rings is 17.71†(5)°. The crystal packing is stabilized by a C-H⋯π inter-action, which connects the mol-ecules into zigzag chains running along the b axis.
