Abstract: 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 - interactions [centroid-centroid distance = 3.8074 (12) Å]. In addition, the crystal structure exhibits a nonclassical intermolecular C-HN hydrogen bond.
