title: Cyclo-hexa-2,5-diene-1,4-dione-1,2,4,5-tetra-fluoro-3,6-diiodo-benzene (1/1).
abstract: The asymmetric unit of the title co-crystal adduct, C(6)H(4)O(2)·C(6)F(4)I(2), comprises a half-mol-ecule each of cyclo-hexa-2,5-diene-1,4-dione and 1,2,4,5-tetra-fluoro-3,6-diiodo-benzene. The C(6)F(4)I(2) mol-ecule is almost planar (r.m.s. deviation = 0.0062 Å). In the crystal, the components are connected through O⋯I halogen bonds [3.017 (11) Å], leading to the formation of wavelike chains along the a axis. The crystal packing also features C-H⋯F inter-actions.
