Self-Assembled Microporous M-HOFs Based on an Octahedral Rhenium Cluster with Benzimidazole

Substitution of apical halide ligands in [{Re6Se8i}X-6(a)](3-) (X = Cl, Br) by benzimidazole (bimzH) accompanied by a self-assembly process leads to the formation of microporous Re(6)based hydrogen-bonded organic frameworks (Re-6-HOFs) constructed on N-H center dot center dot center dot X hydrogen bonds and pi-pi- stacking interactions between bimzH ligands. Re-6-HOFs demonstrate sorption properties with a Brunauer-Emmett-Teller surface area of up to 443 m(2) g(-1) and luminescence with a quantum yield and an emission lifetime of up to 0.16 and 16 mu s, respectively. The compounds obtained complement small groups of transitionmetal cluster-based HOFs, which are a perspective for the development of multifunctional frameworks.
