Synthesis of two new aluminophosphate based layered materials using Tet-A as a structure directing agent

A layered aluminofluorophosphate and a cobalt-aluminophosphate material have been prepared using the azamacrocycle meso-5,7,7,12,14,14-hexamethyl-1,4,8,11-tetraazacyclotetradecane (Tet-A) as a structure-directing agent (SDA). Both were synthesised using hydrothermal techniques and their structures solved using microcrystal X-ray diffraction. The first material, [F, Tet-A]-AlPO-1, has the molecular formula Al10P10O40F2C16N4H38 and crystallises in the orthorhombic space group Pca2(1). Its inorganic layered structure is related to the AlPO-41 (AFO) zeolite structure type. The second material, [Co, Tet-A]-AlPO-2, has the formula Al-4 (PO4)(4) (HPO4)(2).[Co(C16N4H36)].C16N4H38.2H(2)O and crystallises in the triclinic space group P (1) over bar. This material contains a cobalt-Tet-A complex that is covalently bound to the inorganic framework and an uncoordinated Tet-A molecule that is hydrogen bonded to the framework.
