Synthesis and crystal structure of a novel beryllium phosphate open-framework structure

Abstract

The synthesis and crystal structure of a new beryllophosphate (BePO) open-framework structure are reported. The new anionic BePO framework contains regular, one-dimensional eight-ring channels occupied by an organic cation, and secondary channels containing pendant P—OH and Be(OH₂) units. Framework–framework and framework–guest hydrogen bonds are key structural features of this new phase.
