Abstract

In the title compound, CHNO, the 1,2-di-hydro-pyridine ring of the 1,2,7,8-tetra-hydro-iso-quinoline ring system is planar as expected, while the cyclo-hexa-1,3-diene ring has a twist-boat conformation, with Cremer-Pople parameters = 0.367 (2) A, θ = 117.3 (3)° and φ = 327.3 (4)°. The dihedral angles between the best planes through the iso-quinoline ring system and the three phenyl rings are 81.69 (12), 82.45 (11) and 47.36 (10)°. In the crystal, mol-ecules are linked 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 inter-action involving the phenyl H atoms. The role of the inter-molecular inter-actions 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.

摘要

在标题化合物CHNO中,1,2,7,8-四氢异喹啉环系的1,2-二氢吡啶环如预期那样呈平面状,而环己-1,3-二烯环具有扭船构象,其Cremer-Pople参数为 = 0.367 (2) Å,θ = 117.3 (3)°,φ = 327.3 (4)°。通过异喹啉环系的最佳平面与三个苯环之间的二面角分别为81.69 (12)、82.45 (11)和47.36 (10)°。在晶体中,分子通过N-H⋯O和C-H⋯N氢键相连,形成三维网络。此外,晶体堆积以C-H⋯π键为主,其中涉及苯基H原子的相互作用较强。利用Hirshfeld表面分析阐明了分子间相互作用在晶体堆积中的作用,二维指纹图谱表明,对晶体堆积最重要贡献来自H⋯H(46.0%)、C⋯H/H⋯C(35.1%)和N⋯H/H⋯N(10.5%)接触。
