The title compound, C 32 H 23 Cl 2 N, was synthesized via the Ullmann reaction. The orientations of the three aromatic rings attached to the vinyl group are determined by the sp 2 state of the vinyl C atoms. The crystal packing is stabilized by weak CÐHÁ Á Á% interactions.
H -Dicyanobiphenyl, C 14 H 8 N 2 , has a normal structure with a twist angle of 31.8 (2) . The molecules stack with overlapping % systems and form chains held together by antiparallel CÐ NÁ Á ÁCÐN interactions. In addition, there are a number of CÐ HÁ Á ÁN interactions.
H -Diiodobiphenyl, C 12 H 8 I 2 , crystallizes as a homologous isomorph of the high-temperature form of p-diiodobenzene. The molecule is planar and lies on a center of symmetry. Each I atom is in contact with ®ve others at distances between 4.0 and 4.5 A Ê .
The dihedral angle between the benzene rings in the title compound, C 12 H 7 Cl 3 , is 47.25 (4) .
