Materials Data on TmTlO2 by Materials Project
TmTlO2 is Caswellsilverite structured and crystallizes in the trigonal R-3m space group. The structure is three-dimensional. Tm3+ is bonded to six equivalent O2- atoms to form edge-sharing TmO6 octahedra. All Tm–O bond lengths are 2.27 Å. Tl1+ is bonded in a 6-coordinate geometry to six equivalent O2- atoms. All Tl–O bond lengths are 2.94 Å. O2- is bonded in a 6-coordinate geometry to three equivalent Tm3+ and three equivalent Tl1+ atoms.
