1,4-Bis(iodomethyl)benzene

Abstract

The centrosymmetric title compound, C8H8I2, was prepared by metathesis from the dibromo analogue. In the crystal structure, weak C—H...I interactions link the molecules into stacks down the b axis. The structure is further stabilized by short I...I contacts [3.8433 (2) Å], forming undulating sheets in the (101) plane.
