Abstract

In the title compound, C(19)H(16)Cl(4)O(4), the two halves of the mol-ecule are related by a crystallographic twofold rotation axis passing through the central spiro-C atom. The two non-planar six-membered heterocycles both adopt chair conformations, and the dihedral angle between the two benzene rings is 76.6 (1)°. In the crystal structure, inter-molecular C-H⋯O hydrogen bonds link the mol-ecules into chains along the c axis.

摘要

在标题化合物C(19)H(16)Cl(4)O(4)中，分子的两部分通过一个穿过中心螺C原子的晶体学二重旋转轴相关联。两个非平面六元杂环均采用椅式构象，两个苯环之间的二面角为76.6 (1)°。在晶体结构中，分子间的C—H⋯O氢键将分子沿c轴连接成链。
