Materials Data on Tl3PO4 by Materials Project
Tl3PO4 crystallizes in the hexagonal P6_3 space group. The structure is three-dimensional. Tl1+ is bonded in a 3-coordinate geometry to three O2- atoms. There are a spread of Tl–O bond distances ranging from 2.56–2.61 Å. P5+ is bonded in a tetrahedral geometry to four O2- atoms. There is three shorter (1.56 Å) and one longer (1.58 Å) P–O bond length. There are two inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted single-bond geometry to two equivalent Tl1+ and one P5+ atom. In the second O2- site, O2- is bonded in a distorted tetrahedral geometry to three equivalent Tl1+ and one P5+ atom.
