From diiodo Tröger's bases towards halogen-bonded porous organic crystalline materials

Racemic 2,8-diiodo-6H,12H-5,11-methanodibenzodiazocine (rac-1) and racemic 2,8-diiodoethynyl-6H,12H-5,11-methano-dibenzodiazocine (rac-2) proved to be self-complementary tectons that are particularly suitable for the formation of porous supramolecular structures by halogen bonding. Crystals structures of clathrate rac-1·CHCl and rac-2 show channels, which represent 20% of the cell volume, and these are stabilized by strong C-I⋯N and C-I⋯π halogen bonds.This work was financially supported by the Ministerio de Economía y Competitividad (MAT2015-66208-C3-1-P and MAT2014-55205-P) and OTRI 2017/0016.
