Abstract A novel 3D cationic metal–organic framework, {[AgTPB]∙SbF6}n (namely 1), based on AgI and 1,2,4,5-tetra(4-pyridyl) benzene (TPB) was successfully generated under the diffusion synthesis method. The as-synthesized crystal has been investigated and characterized by physicochemical and spectroscopic methods in detail, including single crystal X-ray diffraction, powder X-ray diffraction, UV–Vis spectra, gas/liquid sorption, as well as thermogravimetric analysis. The counter anion SbF6− coming from AgSbF6 exists in the pores of MOF 1. The activated 1 can selectively adsorb CO2 over CH4, and H2O over C2H5OH. Furthermore, it also can be used as a rapid anion exchange MOF for Cr2O72− in water system at room temperature.
