Synthesis and structure of an aluminium 3-aminopropylphosphonate sulfate hydrate

摘要

A new aluminium 3-aminopropylphosphonate sulfate hydrate has been prepared using hydrothermal methods, and its structure solved using microcrystal X-ray diffraction at a synchrotron source. The structure consists of one-dimensional chains of aluminium 3-aminopropylphosphorate with sulfate anions occluded between the chains. It is unusual in compounds of this type to have anionic groups between positively charged aluminium phosphonate units. Further characterisation of the compound has been carried out using magic angle spinning NMR.
