5-(4-Chloro-phen-yl)-3-(2-fur-yl)-1,2,4-triazolo[3,4-a]isoquinoline

In the title mol-ecule, C(20)H(12)ClN(3)O, the triazoloisoquinoline ring system is nearly planar, with an r.m.s. deviation of 0.018 (3) Å and a maximum deviation of 0.034 (3) Å from the mean plane for the triazole ring C atom which is bonded to the benzene ring. The furan and benzene rings are twisted by 59.71 (14) and 66.95 (10)°, respectively, with respect to the mean plane of the triazoloisoquinoline ring system. The mol-ecular conformation is stabilized by an intra-molecular π-π inter-action [centroid-to-centroid distance = 3.5262 (18) Å]. The crystal packing is stabilized by weak C-H⋯π inter-actions and weak π-π inter-actions [centroid-to-centroid distance = 3.9431 (17) Å].
