Aluminium phosphate frameworks with clathrated ethylenediamine: X-ray characterization of Al3P3O11(OH)2·N2C2H8(AlPO4-12)

Abstract

The structure of the AlPO₄-12 memver of the open aluminophosphate frameworks consists of sheets of four-co-ordinate phosphorus and aluminium, [Al^IVP^IVO₄(OH)]^–, alternating, along [100], with slabs of four-co-ordinate phosphorus and five-co-ordinate aluminium, [Al^V₂P^IV₂O₇(OH)]⁺, to form channels in [010] and [001]; the sheets and slabs are linked via Al–O–P linkages with ethylenediamine positioned between them in a fashion suggesting its structure-directing (template) role during synthesis.
