Ortho ‐Carborane‐Derived Halogen‐Bonded Sandwich Complexes

We recently introduced multidentate halogen‐bonding receptors based on C‐iodinated ortho ‐Carborane moieties. Following up on our results in solution, which indicated a second binding event for sub‐stochiometric concentrations of halide guests, we herein present a systematic co‐crystallization study with halides to further evaluate the halogen‐bonding capacities of these halogen‐bonding catalysts. The obtained solid‐state structures include two rare examples of octahedral coordination via halogen bonding of a halide ion by a pair of tridentate receptors.
