Abstract

The title compound, C(14)H(10)Cl(4), is easily crystallized while the other enanti-omorph 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 inter-molecular 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)°

摘要

标题化合物C(14)H(10)Cl(4)很容易结晶，而另一种对映体在尝试结晶时只形成油状物。与外消旋体（ρ ≃ 1.514 Mg m(-3)）相比，标题化合物的密度相当高，ρ ≃ 1.562 Mg m(-3)。这一点得到了以下事实的支持：标题化合物中有两个分子间卤-卤接触，而外消旋化合物只有一个。两个苯环之间的二面角为76.83 (5)°
