Synthesis and structure of aluminophosphate jððCH3Þ3CNH

b,1 b, * b c,d (ESRF) in Grenoble, but the quality of these data did not allow satisfactory refinement. Therefore the structure was refined using high-resolution powder diffraction data, also collected at the ESRF. The structure (P2 /c, a = 9.8922(6) Å, They are usually characterized by an Al/P ratio of one and a neutral three-dimensional aluminophosphate framework of alternating, corner-sharing AlO4 and PO4 tetrahedra. Some members of this AlPO4-family of microporous materials have structures analogous t
