Abstract

The title compound, CHNO, is built up from the planar benzo-diazole unit linked to the benzyl and propynyl substituents. The substituents are rotated significantly out of the benzo-diazole plane, where the benzyl group is inclined by 68.91 (7)° to the benzo-diazole unit. In the crystal, the mol-ecules are linked via inter-molecular C-H⋯O and C-H⋯O (Bnzdzl = benzo-diazole and Bnzy = benz-yl) hydrogen bonds, enclosing (27) ring motifs, into a network consisting of rectangular layers parallel to the plane which are also stacked along the -axis direction being associated through C-H⋯π (ring) inter-actions. The Hirshfeld surface analysis of the crystal structure indicates that the most important contributions for the crystal packing are from H⋯H (43.6%), H⋯C/C⋯H (42.0%) and H⋯O/O⋯H (8.9%) inter-actions.

摘要

标题化合物CHNO由与苄基和丙炔基取代基相连的平面苯并二唑单元构成。取代基显著偏离苯并二唑平面旋转,其中苄基相对于苯并二唑单元倾斜68.91 (7)°。在晶体中,分子通过分子间C-H⋯O和C-H⋯O(Bnzdzl = 苯并二唑,Bnzy = 苄基)氢键相连,形成(27)环模式,构成一个由平行于平面的矩形层组成的网络,这些层也沿轴方向堆叠,通过C-H⋯π(环)相互作用相互关联。晶体结构的 Hirshfeld 表面分析表明,对晶体堆积最重要的贡献来自H⋯H(43.6%)、H⋯C/C⋯H(42.0%)和H⋯O/O⋯H(8.9%)相互作用。
