Abstract

The mol-ecule of the title compound, C(26)H(20)O(4), is located on a twofold rotation axis. The two benzoyl groups are situated in an anti orientation. The dihedral angle between the mean planes of the phenyl ring and the naphthalene ring system is 80.25 (6)°. The phenyl and carbonyl groups in each benzoyl group are almost coplanar. The mol-ecular packing is stabilized by weak C-H⋯O hydrogen bonds and a π-π stacking inter-action between the phenyl rings [centroid-centroid and inter-planar distances of 3.6383 (10) and 3.294 Å, respectively].

摘要

标题化合物C(26)H(20)O(4)的分子位于一个二重旋转轴上。两个苯甲酰基呈反式取向。苯环和萘环体系平均平面之间的二面角为80.25 (6)°。每个苯甲酰基中的苯基和羰基几乎共面。分子堆积通过弱C-H⋯O氢键和苯环之间的π-π堆积相互作用得以稳定[质心-质心距离和平面间距离分别为3.6383 (10)和3.294 Å]。
