Triphenyl(3,4,5-triiodophenyl)-methane.

The crystal structure of the title compound, alternatively called 1,2,3-triiodo-5-(triphenylmethyl)benzene, C₂₅H₁₇I₃, is analysed in terms of I···I and I···π interactions and the herring-bone T motif between phenyl groups. There are two molecules in the asymmetric unit, denoted A and B. Inversionrelated A molecules are connected via an I···π interaction (3.641 Å, to a C-C bond mid-point) to form an I···π dimer, and these dimers are connected through symmetry-independent B molecules via I···I [3.5571 (15) Å] and I···π (3.561 Å, to a C-C bond mid-point) interactions.
