Abstract

The title compound, C(20)H(16)Cl(2)O(2)Se(2), utilizes the symmetry of the crystallographic inversion center. Mol-ecular chains are formed through symmetric C-H⋯Cl inter-actions around inversion centers, mimicking the commonly observed symmetric hydrogen-bonded dimer pattern often found in carboxylic acids.

摘要

标题化合物C(20)H(16)Cl(2)O(2)Se(2)利用了晶体学反演中心的对称性。分子链通过围绕反演中心的对称C-H⋯Cl相互作用形成，模仿了羧酸中常见的对称氢键二聚体模式。
