3-(4-Chloro­phen­yl)-5-phenyl-1,2,4-triazolo[3,4-a]isoquinoline

In the title mol­ecule, C(22)H(14)ClN(3), the triazoloisoquinoline ring system is approximately planar, with an r.m.s. deviation of 0.033 (2) Å and a maximum departure from the mean plane of 0.062 (1) Å for the triazole ring C atom, bonded to the benzene ring. The benzene and phenyl rings are twisted by 57.02 (6) and 62.16 (6)°, respectively, to the mean plane of the triazoloisoquinoline ring system. The mol­ecule is stabilized by a weak intra­molecular π–π inter­action [centroid–centroid distance = 3.7089 (10) Å] between the benzene and phenyl rings. In the crystal structure, weak inter­molecular C—H⋯N hydrogen bonds and C—H⋯π inter­actions link the mol­ecules.
