Title: New thallium iodates-Synthesis, characterization, and calculations of Tl(IO{sub 3}){sub 3} and Tl{sub 4}(IO{sub 3}){sub 6}, [Tl{sup +}{sub 3}Tl{sup 3+}(IO{sub 3}){sub 6}]

Two new thallium iodates have been synthesized, Tl(IO{sub 3}){sub 3} and Tl{sub 4}(IO{sub 3}){sub 6} [Tl{sup +}{sub 3}Tl{sup 3+}(IO{sub 3}){sub 6}], and characterized by single-crystal X-ray diffraction. Both materials were synthesized as phase-pure compounds through hydrothermal techniques using Tl{sub 2}CO{sub 3} and HIO{sub 3} as reagents. The materials crystallize in space groups R-3 (Tl(IO{sub 3}){sub 3}) and P-1 (Tl{sub 4}(IO{sub 3}){sub 6}). Although lone-pairs are observed for both I{sup 5+} and Tl{sup +}, electronic structure calculations indicate the lone-pair on I{sup 5+} is stereo-active, whereas the lone-pair on Tl{sup +} is inert. - Graphical abstract: Visualization of the stereo-active lone-pair (purple) through ELFs for Tl{sub 4}(IO{sub 3}){sub 6}. The spherical nature of the ELFs around the Tl{sup +} cation indicates the lone-pair is inert.
