Sn(PO3)3 crystallizes in the hexagonal P-6c2 space group. Sn(1) is bonded to six equivalent O(2) atoms to form SnO6 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 Sn(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 bent 150 degrees geometry to two equivalent P(1) atoms. In the second O site, O(2) is bonded in a distorted bent 150 degrees geometry to one Sn(1) and one P(1) atom.
Sn(PO3)3 crystallizes in the hexagonal P-6c2 space group. Sn(1) is bonded to six equivalent O(2) atoms to form SnO6 octahedra that share corners with six equivalent P(1)O4 tetrahedra. All Sn(1)-O(2) bond lengths are 2.24 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 Sn(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 1.61 Å. Both P(1)-O(2) bond lengths are 1.51 Å. There are two inequivalent O sites. In the first O site, O(1) is bonded in a bent 150 degrees geometry to two equivalent P(1) atoms. In the second O site, O(2) is bonded in a distorted bent 150 degrees geometry to one Sn(1) and one P(1) atom.
