Zeolite imidazole frameworks (ZIFs) tend to mimic the zeolite structures due to their tetrahedral metal centers and bent ditopic imidazolate linkers. So far, among the 41 ZIF structural types, 10 types are exactly same as those found in zeolites. In the course of searching for new ZIF structural types, we could prepare a new one exhibiting zeolite AFI topology by low-temperature routes from the reactions between zinc salt and imidazole or purine. A single crystal X-ray diffraction analysis revealed that the new ZIF had a similar structure as gme ZIFs with large straight one-dimensional channels. Nitrogen adsorption measurements resulted in a Type-I isotherm, and a BET surface area was estimated to about 1900 m2/g which is the second largest among the known MOF. In this presentation, we also report the gas adsorption and guest inclusion properties of the new ZIF.
