Abstract

A novel family of berylloborophosphates, MIBeBPO (MI, K+, Na+ and NH4 +) with the zeolite analcime (ANA) frameworktopology has been hydrothermally synthesized by using monovalent cations as the templates. The structure of KBeBP2O8 · 1=3H2O (K-BBP-ANA) was solved by single-crystal X-ray diffraction and crystal data for K-BBP-ANA are: M 1/4 254:19, cubic, space group: P213, a = 12.427(6) Å, V = 1919.0(17) Å3= 12, Z = 12, R1 = 0.0768, Rw = 0.1842. The compound is the first BeBPO4 phase with zeolite-ANA structure, which is built of corner-sharing BeO4, BO4, and PO4 tetrahedra. K-BBP-ANA has three-dimensional distorted eight-ring channels along the crystallographic [1 00], [0 1 0] and [00 1] directions. The frameworkcharges of BBP-ANA are balanced by the monovalent cations in the channel. The X-ray powder diffraction patterns show the family of MIBeBPO (MI = K+, Na+ and NH4 + ) are isostructural and their frameworkstructures are thermally stable up to 800 °C.
