Triphenyl(3,4,5-triiodophenyl)methane

The crystal structure of the title compound, alternatively called 1,2,3-triiodo-5-(triphenylmethyl)benzene, C 25 H 17 I 3 , 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. Inversion-related A molecules are connected via an I...π interaction (3.641 A, 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) A] and I...π (3.561 A, to a C-C bond mid-point) interactions.
