This analysis of the title compound, C13H13F2IO3, establishes the orientati
on of (E)-5-(CH=CH-I) as antiperiplanar (ap) to the CDC bond (5-6 position)
of the 2,4-difluorophenyl ring system, with the (E)-5-(CH=CH-I) H atom loc
ated in close proximity (2.17 Angstrom) to the F4 atom of the 2,4-difluorop
henyl moiety.
