5-[(4-Benzyl-1H-1,2,3-triazol-1-yl)meth­yl]-5H-dibenzo[b,f]azepine

In the title compound, C₂₄H₂₀N₄, the azepine ring adopts a boat conformation and the dihedral angle between the benzene rings fused to it is 57.95 (8)°. The bond-angle sum at the azepine N atom is 346.6°, indicating a significant deviation from planarity. The triazole ring subtends a dihedral angle of 71.45 (10)° with the terminal phenyl group. A weak intra­molecular C—H...N_a (a = azepine) inter­action occurs, which closes an S(6) ring.
