Structures and Templating Effect in the Formation of 2D Layered Aluminophosphates with Al3P4O163- Stoichiometry

The structural features of a family of layered aluminophosphates with Al 3 P 4 O 16 3 - stoichiometry (denoted L - n ) have been discussed. Their 2D sheets are stabilized by protonated organic amines through H-bonding interactions with certain regularity. The templating ability of various organic amines for the experimental inorganic layers is investigated in terms of the energies of the host−template interactions. Some experimental phenomena, such as the packing sequence of the inorganic layers and the co-templating role of two types of templates on the formation of some structures, can be explained by energy calculation results. Some organic templates that can potentially direct the formation of a given host can be predicted. This further assists in the rational synthesis of 2D layered compounds with specific structures.
