A series of 12-phenyl-closo-thiaboranes (12-(4-X-C6H4)-closo-1-SB11H10, where X = OMe (2), SMe (3), Ph (4), and NMe2 (5)) has been prepared. Except for 2, all compounds exhibit a chalcogen bond thiaborane to the phenyl ring or neighboring molecule as major supramolecular structural motif. 5, having strongest (-12.47 kcal/mol) structure-making intermolecular interaction via noncovalent S···π(phenyl) bond, was crystallized from different solvents in form various solvatopolymorphs. n-Hexane diethyl ether can be removed 5 easily upon formation porous material with large cavities (up 20.5% unit cell). This first stable useful noncovalently bound organic framework an ultramicroporous structure exhibits molecular sieve effect. The selective repeatable adsorption CO2 n-hexane explained on basis cooperative consecutive machine-like interactions quadrupolar B-H amino groups inside rectangular cavities.
