Abstract: [{Re-I(CO)(3)(Hbim)}(3)(tpta)](2) (1, Hbim(-) = 2,2'-biimidazolate monoanion, tpta = 2,4,6-tripyridyl-1,3,5-triazine) was prepared as a nano-space supramolecule by using a new group of H-bonded coordination capsules. The hamburger bun-shaped half unit [{Re-I(CO)(3)(Hbim)}(3)(tpta)] contains six intermolecular H-bonds of Hbim(-) ligands with complementary dual NH center dot center dot center dot N types, and three [Re-I(CO)(3)(Hbim)] are coordinated by bridging tridentate tpta. Interestingly, mechanical grinding easily would convert single crystals of 1 to an amorphous state with minor crystallinity while maintaining the nano-space pores. The ground sample can reversibly uptake and release small molecules such as CO2 and (CH2Cl)(2).
