Sn3O8 crystallizes in the orthorhombic Immm space group. There are two inequivalent Sn sites. In the first Sn site, Sn(1) is bonded to two equivalent O(1), two equivalent O(2), and two equivalent O(3) atoms to form a mixture of corner and edge-sharing SnO6 octahedra. The corner-sharing octahedral tilt angles range from 39-51°. In the second Sn site, Sn(2) is bonded to two equivalent O(2) and four equivalent O(1) atoms to form corner-sharing SnO6 octahedra. The corner-sharing octahedral tilt angles range from 39-51°. There are three inequivalent O sites. In the first O site, O(1) is bonded in a bent 150 degrees geometry to one Sn(1) and one Sn(2) atom. In the second O site, O(2) is bonded in a trigonal planar geometry to one Sn(2) and two equivalent Sn(1) atoms. In the third O site, O(3) is bonded in a water-like geometry to two equivalent Sn(1) atoms.
