A new zeolitic topology with sixteen-membered ring and multidimensional large pore channels

A new zeolitic topology with membered ring and multidimensional pore channels has been demonstrated. The new topology consists 3- and 16-rings, new loop configurations, and multidimensional intersecting large pore channels. The two tetrahedral imidazolate framework (TIF) zeolites were synthesized by using solverthermal reaction. The crystal structure of TIFs were determined by using single X-ray diffraction and X-ray powder diffraction patterns. The co-existence of 3- and 16-membered rings can be used to produce a framework with low-framework density and multi-dimensional channels. A weight loss at 30-140 °C of TIF-1Zn was observed during thermal gravimetric analysis (TGA). A gas adsorption measurement technique was applied to determine the permanent porosity of TIF-1Zn.
