摘要
[{ReI(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 [{ReI(CO)3(Hbim)}3(tpta)] contains six intermolecular H-bonds of Hbim− ligands with complementary dual NH⋯N types, and three [ReI(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.
