Abstract: The SAPO-5 single crystals with the size of 150μ×100μm crystallized in space group P6cc with a=1.3802 nm and c=0.8503 nm.The crystal structure was refined to Rw=0.043.F- anions are located on the wall of the framework between two four-membered rings.Electron probe microanalysis (EPMA) shows that silicon is only substituted for phosphorus.
