Title: Covalent guest-framework interactions in heavy metal sodalites: Structure and properties of thallium and silver sodalite

Abstract

Covalent bonds between the heavy metal cations and the aluminosilicate framework have been discovered to be the cause of distinct structural characteristics in anhydrous sodalites Ag{sub 6}[AlSiO{sub 4}]{sub 6} and Tl{sub 6}[AlSiO{sub 4}]{sub 6} that differ significantly from their alkali metal containing analogues. Evidence of guest-framework bonding interactions include interatomic distances, shifted IR bands, and quadrupole coupling of aluminum. This bonding results in a reduction of the unit cell size, and a locked in static disorder of the cations. Also of interest are the short Tl-Tl distances seen in Tl{sub 6}[AlSiO{sub 4}]{sub 6}. These could indicate the formation of Tl{sub 3}{sup 3+} species in each cage, resulting in a bcc lattice of ionic thallium clusters. Low-temperature synchrotron powder diffraction data, multiple quantum magic-angle spinning (MQ-MAS) NMR, and FTIR studies are presented.
