1,4-Bis(4-chlorophenylseleno)-2,5-dimethoxybenzene
نویسندگان
چکیده
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.
