Crystal structure of (E)-1-(4-tert-butyl­phen­yl)-2-(4-iodo­phen­yl)ethene

The title compound, C(18)H(19)I, crystallized with two independent mol­ecules (A and B) in the asymmetric unit. Both mol­ecules 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 mol­ecule A, but only 1.0 (6)° in mol­ecule B. In the crystal, the individual mol­ecules are linked by C—I⋯π inter­actions forming zigzag A and zigzag B chains propagating along [001]. The structure was refined as an inversion twin [Flack parameter = 0.48 (2)].
