Abstract
The title compound, C14H10Cl4, is easily crystallized while the other enantiomorph only forms an oil upon crystallization attempts. The title compound has a considerably higher density, ρ ≃ 1.562 Mg m−3 compared to the racemic substance, ρ ≃ 1.514 Mg m−3. This is supported by the fact there are two intermolecular halogen–halogen contacts in the title compound compared with only one the racemic compound. The dihedral angle between the two phenyl rings is 76.83 (5)°
