1,1,1-Trichloro-2,2-bis-(4-iodo-phen-yl)ethane.
In the structure of the title compound, C(14)H(9)Cl(3)I(2), which is the 4-iodo-phenyl analogue of the insecticide DDT [1,1,1-tri-chloro-2,2-bis-(4-chloro-phen-yl)ethane], isomorphism between the two compounds has been confirmed. In the mol-ecule, the dihedral angle between the planes of the two benzene rings is 65.8 (4)° which compares with 64.7 (7)° in DDT.
