The material structure described by Na6S2O9 crystallizes in the cubic Fm-3m space group. Na(1) is bonded in a 5-coordinate geometry to one O(1) and four equivalent O(2) atoms. S(1) is bonded in a tetrahedral geometry to four equivalent O(2) atoms. There are two inequivalent O sites. In the first O site, O(1) is bonded in an octahedral geometry to six equivalent Na(1) atoms. In the second O site, O(2) is bonded in a 4-coordinate geometry to three equivalent Na(1) and one S(1) atom. is represented by the CIF file [CIF]
