Materials Data on CsPPbO4 by Materials Project
CsPbPO4 crystallizes in the orthorhombic Pnma space group. The structure is three-dimensional. Cs1+ is bonded in a 7-coordinate geometry to seven O2- atoms. There are a spread of Cs–O bond distances ranging from 3.02–3.28 Å. Pb2+ is bonded in a 7-coordinate geometry to seven O2- atoms. There are a spread of Pb–O bond distances ranging from 2.39–3.11 Å. P5+ is bonded in a tetrahedral geometry to four O2- atoms. There are a spread of P–O bond distances ranging from 1.55–1.58 Å. There are three inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted single-bond geometry to one Cs1+, three equivalent Pb2+, and one P5+ atom. In the second O2- site, O2- is bonded in a single-bond geometry to two equivalent Cs1+, two equivalent Pb2+, and one P5+ atom. In the third O2- site, O2- is bonded in a distorted single-bond geometry to two equivalent Cs1+, one Pb2+, and one P5+ atom.
