Abstract
In the title compound, C(36)H(28)O(5), the terminal benzene rings are twisted at dihedral angles of 6.75 (12), 70.86 (14) and 82.02 (12)° with the respect to the central plana r[maximum deviation = 0.070 (3) Å] chromen-4-one ring system. In the crystal structure, π-π stacking is observed between parallel benzene rings of adjacent mol-ecules [centroid-centroid distance = 3.7459 (16) Å].
摘要
在标题化合物C(36)H(28)O(5)中，末端苯环相对于中心平面[最大偏差 = 0.070 (3) Å]的色烯-4-酮环系统扭转的二面角分别为6.75 (12)°、70.86 (14)°和82.02 (12)°。在晶体结构中，观察到相邻分子的平行苯环之间存在π-π堆积作用[质心-质心距离 = 3.7459 (16) Å]。
