KZn(PO3)3 crystallizes in the hexagonal P-6c2 space group. K(1) is bonded in a 6-coordinate geometry to six equivalent O(1) atoms. Zn(1) is bonded to six equivalent O(1) atoms to form ZnO6 octahedra that share corners with six equivalent P(1)O4 tetrahedra. P(1) is bonded to two equivalent O(1) and two equivalent O(2) atoms to form PO4 tetrahedra that share corners with two equivalent Zn(1)O6 octahedra and corners with two equivalent P(1)O4 tetrahedra. The corner-sharing octahedral tilt angles are 42°. There are two inequivalent O sites. In the first O site, O(1) is bonded in a 3-coordinate geometry to one K(1), one Zn(1), and one P(1) atom. In the second O site, O(2) is bonded in a bent 150 degrees geometry to two equivalent P(1) atoms.
KZn(PO3)3 crystallizes in the hexagonal P-6c2 space group. K(1) is bonded in a 6-coordinate geometry to six equivalent O(1) atoms. All K(1)-O(1) bond lengths are 2.80 Å. Zn(1) is bonded to six equivalent O(1) atoms to form ZnO6 octahedra that share corners with six equivalent P(1)O4 tetrahedra. All Zn(1)-O(1) bond lengths are 2.12 Å. P(1) is bonded to two equivalent O(1) and two equivalent O(2) atoms to form PO4 tetrahedra that share corners with two equivalent Zn(1)O6 octahedra and corners with two equivalent P(1)O4 tetrahedra. The corner-sharing octahedral tilt angles are 42°. Both P(1)-O(1) bond lengths are 1.50 Å. There is one shorter (1.61 Å) and one longer (1.62 Å) P(1)-O(2) bond length. There are two inequivalent O sites. In the first O site, O(1) is bonded in a 3-coordinate geometry to one K(1), one Zn(1), and one P(1) atom. In the second O site, O(2) is bonded in a bent 150 degrees geometry to two equivalent P(1) atoms.
