Na2Hg3(S2O)2 crystallizes in the orthorhombic Ibam space group. Na(1) is bonded in a 6-coordinate geometry to four equivalent S(1) and two equivalent O(1) atoms. There are two inequivalent Hg sites. In the first Hg site, Hg(1) is bonded in a 4-coordinate geometry to four equivalent S(1) atoms. In the second Hg site, Hg(2) is bonded in a 2-coordinate geometry to two equivalent S(1) atoms. S(1) is bonded in a distorted single-bond geometry to two equivalent Na(1), one Hg(1), one Hg(2), and one O(1) atom. O(1) is bonded to two equivalent Na(1) and two equivalent S(1) atoms to form corner-sharing ONa2S2 tetrahedra.
Na2Hg3(S2O)2 crystallizes in the orthorhombic Ibam space group. Na(1) is bonded in a 6-coordinate geometry to four equivalent S(1) and two equivalent O(1) atoms. There are two shorter (2.93 Å) and two longer (2.98 Å) Na(1)-S(1) bond lengths. There is one shorter (2.58 Å) and one longer (2.74 Å) Na(1)-O(1) bond length. There are two inequivalent Hg sites. In the first Hg site, Hg(1) is bonded in a 4-coordinate geometry to four equivalent S(1) atoms. All Hg(1)-S(1) bond lengths are 2.82 Å. In the second Hg site, Hg(2) is bonded in a 2-coordinate geometry to two equivalent S(1) atoms. Both Hg(2)-S(1) bond lengths are 2.97 Å. S(1) is bonded in a distorted single-bond geometry to two equivalent Na(1), one Hg(1), one Hg(2), and one O(1) atom. The S(1)-O(1) bond length is 1.76 Å. O(1) is bonded to two equivalent Na(1) and two equivalent S(1) atoms to form corner-sharing ONa2S2 tetrahedra.
