The title achiral compound, C(35)H(34)O(7), crystallizes in the chiral monoclinic space group P2(1). The molecules are densely packed to form a helical assembly along the crystallographic twofold screw axis via C-H···O and C-H···π interactions. Interestingly, the unit-translated helical chains are loosely connected via a rather uncommon edge-to-edge Ph-H···H-Ph short contact (H···H = 2.33 Å).
标题非手性化合物C(35)H(34)O(7)结晶于手性单斜空间群P2(1)中。分子通过C-H···O和C-H···π相互作用紧密堆积，沿晶体学二重螺旋轴形成螺旋组装体。有趣的是，单位平移的螺旋链通过一种相当罕见的边对边Ph-H···H-Ph短接触（H···H = 2.33 Å）松散连接。
