Materials Data on CsZnPO4 by Materials Project

CsZnPO4 crystallizes in the orthorhombic Pnma space group. The structure is three-dimensional. Cs1+ is bonded in a 8-coordinate geometry to eight O2- atoms. There are a spread of Cs–O bond distances ranging from 3.18–3.48 Å. Zn2+ is bonded to four O2- atoms to form ZnO4 tetrahedra that share corners with four equivalent PO4 tetrahedra. There is three shorter (1.95 Å) and one longer (1.97 Å) Zn–O bond length. P5+ is bonded to four O2- atoms to form PO4 tetrahedra that share corners with four equivalent ZnO4 tetrahedra. There is two shorter (1.54 Å) and two longer (1.56 Å) P–O bond length. There are three inequivalent O2- sites. In the first O2- site, O2- is bonded in a 2-coordinate geometry to two equivalent Cs1+, one Zn2+, and one P5+ atom. In the second O2- site, O2- is bonded in a distorted bent 150 degrees geometry to two equivalent Cs1+, one Zn2+, and one P5+ atom. In the third O2- site, O2- is bonded in a distorted linear geometry to two equivalent Cs1+, one Zn2+, and one P5+ atom.
