In the title mol­ecule, C23H14N4, the triazoloisoquinoline ring system is nearly planar, with an r.m.s. deviation of 0.038 (2) Å and a maximum deviation of −0.030 (2) Å from the mean plane of the triazole ring C atom which is bonded to the benzene ring. The benzene and phenyl rings are twisted by 57.65 (8) and 53.60 (9)°, respectively, with respect to the mean plane of the triazoloisoquinoline ring system. In the crystal structure, mol­ecules are linked by weak aromatic π–π inter­actions [centroid–centroid distance = 3.8074 (12) Å]. In addition, the crystal structure exhibits a nonclassical inter­molecular C—H⋯N hydrogen bond.
