Abstract

(NH₄)₂[ZN₂(O₃PCH₂CH₂COO)₂]⋅5 H₂O (BIRM‐1) is a new metal phosphonate material, synthesized through a simple hydrothermal reaction between zinc nitrate and 3‐phosphonopropionic acid, using urea and tetraethylammonium bromide as the reaction medium. In common with other metal–organic framework materials, BIRM‐1 has a large three‐dimensional porous structure providing potential access to a high internal surface area. Unlike most others, it has the advantage of containing ammonium cations within the pores and has the ability to undergo cation exchange. Additionally, BIRM‐1 also exhibits a reversible dehydration behavior involving an amorphization‐recrystallization cycle. The ability to undergo ion exchange and dynamic structural behavior are of interest in their own right, but also increase the range of potential applications for this material. Here the crystal structure of this new metal phosphonate and its ion exchange behavior with K⁺ as an exemplar are studied in detail, and its unusual structure‐reviving property reported.
