Abstract
The crystal packing is established through weak interactions of three types. The first one is of the type Ï ÃÂ Ï interactions, from symmetry operation, between the centroids. The second one is of the type CXâ¯Ï interactions. And the last type is an anomalous intermolecular interaction between halogens, CXâ¯XC, with bond distances smaller than the sum of the van der Waals radii. The conformation on the CC bond is trans and the dihedral angle between the aromatic rings is (with esd approximate) 18.1(3)°.
