Materials Data on SbPO4 by Materials Project

SbPO4 crystallizes in the monoclinic P2_1/m space group. The structure is two-dimensional and consists of one SbPO4 sheet oriented in the (0, 0, 1) direction. Sb3+ is bonded in a rectangular see-saw-like geometry to four O2- atoms. There are a spread of Sb–O bond distances ranging from 2.03–2.22 Å. P5+ is bonded in a tetrahedral geometry to four O2- atoms. There are a spread of P–O bond distances ranging from 1.54–1.58 Å. There are three inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted bent 150 degrees geometry to one Sb3+ and one P5+ atom. In the second O2- site, O2- is bonded in a distorted bent 150 degrees geometry to one Sb3+ and one P5+ atom. In the third O2- site, O2- is bonded in a bent 120 degrees geometry to one Sb3+ and one P5+ atom.
