In the title molecule, C22H14ClN3, 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 weak intermolecular C—H⋯N hydrogen bonds and C—H⋯π interactions link the molecules.

2-(3-Phenylisoquinolin-1-yl)hydrazine (1 mmol) was condensed with, 4-chlorobenzaldehyde (1.1 mmol) under refluxing conditions in isopropanol (10 ml) solvent to give the corresponding hydrazone in high yield. After removal of the solvent the compound was then oxidatively cyclized in nitrobenzene (10 ml) at 473 K. The product was recrystallized from dichlomethane to give block-shaped crystals.
H atoms were placed at calculated positions with C–H = 0.93 Å and were included in the
in the riding model approximation, with Uiso(H) = 1.2Ueq(C).As part of our search for new isoquinoline analogues, we focused on the synthesis of the titled compound, which
is reported.In the title molecule (I), Fig. 1, the triazoloisoquinoline ring system (N1–N3/C1–C9/C16) 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 C16 atom, bonded to the benzene ring (C17–C22). The benzene (C17–C22) and phenyl (C10–C15) rings are twisted by 57.02 (6) and 62.16 (6) ° with respect to the mean plane of the triazoloisoquinoline ring system. The dihedral angle betwen the benzene (C17–C22) and phenyl (C10–C15) rings is 22.21 (8)° .
The molecule is stabilized by a weak intramolecular π-π interaction [Cg4···Cg5(x, y, z) = 3.7089 (10) Å; Cg4 and Cg5 are the centroids of the rings C10–C15 and C17–C22, respectively]. In the weak intermolecular C—H···N hydrogen bonds and C—H···π interactions (Table 1, Fig. 2) link the molecules to each other.

Geometry. All esds (except the esd in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell esds are taken into account individually in the estimation of esds in distances, angles and torsion angles; correlations between esds in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell esds is used for estimating esds involving l.s. planes. |
Refinement. Refinement of F2 against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F2, conventional R-factors R are based on F, with F set to zero for negative F2. The threshold expression of F2 > σ(F2) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F2 are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger. |

As part of our search for new isoquinoline analogues, we focused on the synthesis of the titled compound, which crystal structure is reported.
In the title molecule (I), Fig. 1, the triazoloisoquinoline ring system (N1–N3/C1–C9/C16) 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 C16 atom, bonded to the benzene ring (C17–C22). The benzene (C17–C22) and phenyl (C10–C15) rings are twisted by 57.02 (6) and 62.16 (6) ° with respect to the mean plane of the triazoloisoquinoline ring system. The dihedral angle betwen the benzene (C17–C22) and phenyl (C10–C15) rings is 22.21 (8)° .
The molecule is stabilized by a weak intramolecular π-π interaction [Cg4···Cg5(x, y, z) = 3.7089 (10) Å; Cg4 and Cg5 are the centroids of the rings C10–C15 and C17–C22, respectively]. In the crystal structure, weak intermolecular C—H···N hydrogen bonds and C—H···π interactions (Table 1, Fig. 2) link the molecules to each other.
