The material described by NaS2O4 crystallizes in the monoclinic C2 space group. Na(1) is bonded to two equivalent O(2), two equivalent O(3), and two equivalent O(4) atoms to form face-sharing NaO6 octahedra. There are two inequivalent S sites. In the first S site, S(1) is bonded in a water-like geometry to one S(1) and one S(2) atom. In the second S site, S(2) is bonded in a distorted trigonal non-coplanar geometry to one S(1), one O(1), one O(2), and one O(3) atom. There are four inequivalent O sites. In the first O site, O(1) is bonded in a single-bond geometry to one S(2) atom. In the second O site, O(2) is bonded in a 3-coordinate geometry to two equivalent Na(1) and one S(2) atom. In the third O site, O(3) is bonded in a 3-coordinate geometry to two equivalent Na(1) and one S(2) atom. In the fourth O site, O(4) is bonded in an L-shaped geometry to two equivalent Na(1) atoms. is represented by the CIF card [CIF]
