Crystal structure of ( E )-1-(4- tert -butyl-phen-yl)-2-(4-iodo-phen-yl)ethene.

Abstract

The title compound, C<inf>18</inf>H<inf>19</inf>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)]. Show more
