Materials Data on TmPO4 by Materials Project
TmPO4 is Zircon structured and crystallizes in the tetragonal I4_1/amd space group. The structure is three-dimensional. Tm3+ is bonded in a 8-coordinate geometry to eight equivalent O2- atoms. There are four shorter (2.29 Å) and four longer (2.36 Å) Tm–O bond lengths. P5+ is bonded in a tetrahedral geometry to four equivalent O2- atoms. All P–O bond lengths are 1.55 Å. O2- is bonded in a 1-coordinate geometry to two equivalent Tm3+ and one P5+ atom.
