(a) C—I⋯N halogen bonding in the series C2I2·DABCO, C2H2I2·DABCO and C2H4I2·DABCO (Torubaev & Skabitskiy, 2022). (b) Polybromoferrocenes – multiple halogen-containing interactions (Blockhaus & Sünkel, 2022). (c) C—I⋯O halogen bonding and π-stacking in flexible NPTO (Wang et al., 2023). (d) Bending crystals of 4-halobenzonitrile containing C—X⋯N≡C halogen bonds (Veluthaparambath et al., 2022). (e) C—I⋯S halogen-bonded cocrystals – links to the nucleophilic substitution reaction (Mosquera et al., 2023). All figures are reproduced from the cited references with permission. |
