Crystal structure of hexachlorothallate within a caesium chloride–phosphotungstate lattice Cs9(TlCl6)(PW12O40)2·9CsCl

Abstract

Crystal formation of caesium thallium chloride phosphotungstates, Cs9(TlCl6)(PW12O40)2·9CsCl showcases the ability to capture and crystallize octahedral complexes via the use of polyoxometalates (POMs). The large number of caesium chlorides allows for the POM [α-PW12O40]3− to arrange itself in a cubic close-packing lattice extended framework, in which the voids created enable the capture of the [TlCl6]3− complex.
