Cotemplating ionothermal synthesis of a new open-framework aluminophosphate with unique Al/P ratio of 6/7

Contemplaitng ionothermal synthesis of new open-framework aluminophosphate compound with unique AI/P ratio of 6/7 was demonstrated by using aromatic co-templates. Singal-crystal structural analysis found that the structure of co-templates consist of an anionic open framework and the protonated co-template cations act as the templates to compensate the negative changes of the inorganic framework. The bond lengths in co-templates are found to be within the ranges of aluminophosphate and the alternating connection of Al-centered polyhedra and P-centered tertahedra constructs the open-framework structure of the co-template. The aluminophosphate cation and the protonated aluminophosphate cation are found to coexist in the intersection of the tridirectional channels in the structire of the co-template.
