The compound described by Na4S2O5 crystallizes in the triclinic P1 space group. There are four inequivalent Na sites. In the first Na site, Na(1) is bonded in a 6-coordinate geometry to one S(1), one O(1), one O(3), one O(5), and two equivalent O(4) atoms. In the second Na site, Na(2) is bonded in a 4-coordinate geometry to one O(1), one O(2), one O(3), one O(4), and one O(5) atom. In the third Na site, Na(3) is bonded in a 5-coordinate geometry to one O(1), one O(2), one O(3), one O(4), and one O(5) atom. In the fourth Na site, Na(4) is bonded in a 3-coordinate geometry to one O(1), one O(3), and two equivalent O(2) atoms. There are two inequivalent S sites. In the first S site, S(1) is bonded in a distorted water-like geometry to one Na(1), one O(1), and one O(2) atom. In the second S site, S(2) is bonded in a distorted trigonal non-coplanar geometry to one O(3), one O(4), and one O(5) atom. There are five inequivalent O sites. In the first O site, O(1) is bonded in a 5-coordinate geometry to one Na(1), one Na(2), one Na(3), one Na(4), and one S(1) atom. In the second O site, O(2) is bonded in a 5-coordinate geometry to one Na(2), one Na(3), two equivalent Na(4), and one S(1) atom. In the third O site, O(3) is bonded in a 5-coordinate geometry to one Na(1), one Na(2), one Na(3), one Na(4), and one S(2) atom. In the fourth O site, O(4) is bonded to one Na(2), one Na(3), two equivalent Na(1), and one S(2) atom to form distorted corner-sharing ONa4S trigonal bipyramids. In the fifth O site, O(5) is bonded in a 4-coordinate geometry to one Na(1), one Na(2), one Na(3), and one S(2) atom. is represented by the CIF file [CIF]
