The material described by KZnPO4 crystallizes in the orthorhombic Pna2_1 space group. K(1) is bonded in a 9-coordinate geometry to two equivalent O(1), two equivalent O(3), two equivalent O(4), and three equivalent O(2) 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 4-coordinate geometry to two equivalent K(1), one Zn(1), and one P(1) atom. In the second O site, O(2) is bonded in a distorted linear geometry to three equivalent K(1), one Zn(1), and one P(1) atom. In the third O site, O(3) is bonded in a 4-coordinate geometry to two equivalent K(1), one Zn(1), and one P(1) atom. In the fourth O site, O(4) is bonded in a 2-coordinate geometry to two equivalent K(1), one Zn(1), and one P(1) atom. is represented by the Crystallographic Information File (CIF) [CIF]
