A reactive template in the synthesis of a novel layered aluminium phosphate (Al3P4O16)3–[NH3(CH2)5NH3]2+(C5H10NH2)+

Abstract
Starting from 1,5-diaminopentane as template it is possible to produce a novel microporous layered aluminophosphate (Al:P = 0.75) in which there are two distinct kinds of eight-membered rings within the layers: those that are approximately circular (diameter 7.0 Å) accommodate piperidinium ions, while the elliptical ones (ca. 5.9–8.0 Å) contain 1,5-diammoniumpentane ions.
