The material structure described by Na3OsH2O6 crystallizes in the monoclinic P2_1/m space group. There are two inequivalent Na sites. In the first Na site, Na(1) is bonded in a 5-coordinate geometry to one O(2), two equivalent O(3), and two equivalent O(4) atoms. In the second Na site, Na(2) is bonded in a 6-coordinate geometry to one O(1), one O(2), two equivalent O(3), and two equivalent O(4) atoms. Os(1) is bonded in a distorted octahedral geometry to one O(1), one O(2), two equivalent O(3), and two equivalent O(4) atoms. H(1) is bonded in a single-bond geometry to one O(4) atom. There are four inequivalent O sites. In the first O site, O(1) is bonded in a 3-coordinate geometry to two equivalent Na(2) and one Os(1) atom. In the second O site, O(2) is bonded in a 2-coordinate geometry to one Na(1), two equivalent Na(2), and one Os(1) atom. In the third O site, O(3) is bonded in a distorted see-saw-like geometry to one Na(1), two equivalent Na(2), and one Os(1) atom. In the fourth O site, O(4) is bonded in a distorted single-bond geometry to one Na(1), two equivalent Na(2), one Os(1), and one H(1) atom. is represented by the CIF file [CIF]
