Relative importance of X...O=C vs. X...X halogen bonding as structural determinants in 4-halotriaroylbenzenes.
The structures of 4-chloro- and 4-bromotribenzoylbenzene, as well as a solid solution prepared from these two components, are isomorphous and dominated by C-X...O=C interactions, whereas type-II I...I interactions are important in the 4-iodo derivative.
