CsZnPO4 crystallizes in the orthorhombic Pna2_1 space group. Cs(1) is bonded in a 8-coordinate geometry to two equivalent O(1), two equivalent O(2), two equivalent O(3), and two equivalent O(4) atoms. Zn(1) is bonded to one O(1), one O(2), one O(3), and one O(4) atom to form ZnO4 tetrahedra that share corners with four equivalent P(1)O4 tetrahedra. P(1) is bonded to one O(1), one O(2), one O(3), and one O(4) atom to form PO4 tetrahedra that share corners with four equivalent Zn(1)O4 tetrahedra. There are four inequivalent O sites. In the first O site, O(1) is bonded in a 2-coordinate geometry to two equivalent Cs(1), one Zn(1), and one P(1) atom. In the second O site, O(2) is bonded in a distorted bent 150 degrees geometry to two equivalent Cs(1), one Zn(1), and one P(1) atom. In the third O site, O(3) is bonded in a 2-coordinate geometry to two equivalent Cs(1), one Zn(1), and one P(1) atom. In the fourth O site, O(4) is bonded in a distorted linear geometry to two equivalent Cs(1), one Zn(1), and one P(1) atom.
