The title mol-ecule, C(26)H(30)O(9)S(3), adopts an extended conformation whereby two approximately parallel benzene rings [dihedral angle = 8.32 (10)°] are orientated in opposite directions along the pseudo-threefold axis through the central quaternary C atom, while a third ring occupies a position mid-way and face-on to these rings [dihedral angles = 82.28 (10) and 78.81 (7)°]. The crystal packing is dominated by C-H⋯O contacts and π-π inter-actions [ring centroid distance = 3.6902 (12) Å].
标题分子C(26)H(30)O(9)S(3)呈伸展构象,其中两个近似平行的苯环[二面角 = 8.32 (10)°]沿穿过中心季碳原子的伪三重轴方向相反排列,而第三个环位于这两个环中间且与之面对面[二面角 = 82.28 (10) 和78.81 (7)°]。晶体堆积主要由C—H⋯O接触和π–π相互作用主导[环心距 = 3.6902 (12) Å]。
