1,4-Bis(4-chlorophenylseleno)-2,5-dimethoxybenzene

H. O. Sørensen and N. Stuhr-Hansen

Abstract: The title compound, C₂₀H₁₆Cl₂O₂Se₂, utilizes the symmetry of the crystallographic inversion center. Molecular chains are formed through symmetric C-HCl interactions around inversion centers, mimicking the commonly observed symmetric hydrogen-bonded dimer pattern often found in carboxylic acids.
