In the title compound, CHClO the dihedral angle between the coumarin ring system [maximum deviation = 0.023 (1) Å] and the benzene ring is 73.95 (8)°. In the crystal, π-π inter-actions link the dimers into a three-dimensional framework. A quantum chemical calculation is in generally good agreement with the observed structure, although the calculated dihedral angle between the ring systems (85.7%) is somewhat larger than the observed value [73.95 (8)°]. Hirshfeld surface analysis has been used to confirm and qu-antify the supra-molecular inter-actions.
在标题化合物CHClO中,香豆素环系[最大偏差 = 0.023 (1) Å]与苯环之间的二面角为73.95 (8)°。在晶体中,π-π相互作用将二聚体连接成三维框架。量子化学计算结果与观测结构总体上吻合良好,尽管计算得到的环系间二面角(85.7%)略大于观测值[73.95 (8)°]。 Hirshfeld表面分析已用于确认和量化超分子相互作用。
