title: Crystal structure of (E)-1-(4-tert-butyl-phen-yl)-2-(4-iodo-phen-yl)ethene.
abstract: The title compound, C18H19I, crystallized with two independent mol-ecules (A and B) in the asymmetric unit. Both mol-ecules have an E conformation about the bridging C=C bond. They differ in the orientation of the two benzene rings; the dihedral angle being 12.3 (5)° in mol-ecule A, but only 1.0 (6)° in mol-ecule B. In the crystal, the individual mol-ecules are linked by C-I⋯π inter-actions forming zigzag A and zigzag B chains propagating along [001]. The structure was refined as an inversion twin [Flack parameter = 0.48 (2)].
