The material described by SnTe3O8 crystallizes in the cubic Ia-3 space group. Sn(1) is bonded in an octahedral geometry to six equivalent O(2) atoms. Te(1) is bonded in a distorted see-saw-like geometry to two equivalent O(1) and two equivalent O(2) atoms. There are two inequivalent O sites. In the first O site, O(1) is bonded in a trigonal planar geometry to three equivalent Te(1) atoms. In the second O site, O(2) is bonded in a distorted bent 120 degrees geometry to one Sn(1) and one Te(1) atom. is represented by the CIF file [CIF]
