Crystal structure and Hirshfeld surface analysis of 3-amino-1-oxo-2,6,8-triphenyl-1,2,7,8-tetra­hydro­iso­quinoline-4-carbo­nitrile

In the title compound, C(28)H(21)N(3)O, the 1,2-di­hydro­pyridine ring of the 1,2,7,8-tetra­hydro­iso­quinoline ring system is planar as expected, while the cyclo­hexa-1,3-diene ring has a twist-boat conformation, with Cremer–Pople parameters Q (T) = 0.367 (2) A, θ = 117.3 (3)° and φ = 327.3 (4)°. The dihedral angles between the best planes through the iso­quinoline ring system and the three phenyl rings are 81.69 (12), 82.45 (11) and 47.36 (10)°. In the crystal, mol­ecules are linked via N—H⋯O and C—H⋯N hydrogen bonds, forming a three-dimensional network. Furthermore, the crystal packing is dominated by C—H⋯π bonds with a strong inter­action involving the phenyl H atoms. The role of the inter­molecular inter­actions in the crystal packing was clarified using Hirshfeld surface analysis, and two-dimensional fingerprint plots indicate that the most important contributions to the crystal packing are from H⋯H (46.0%), C⋯H/H⋯C (35.1%) and N⋯H/H⋯N (10.5%) contacts.
