K2OsO6 crystallizes in the tetragonal I4/m space group. K(1) is bonded in a 8-coordinate geometry to four equivalent O(1) and four equivalent O(2) atoms. Os(1) is bonded in an octahedral geometry to two equivalent O(1) and four equivalent O(2) atoms. There are two inequivalent O sites. In the first O site, O(2) is bonded in a distorted single-bond geometry to two equivalent K(1) and one Os(1) atom. In the second O site, O(1) is bonded in a distorted single-bond geometry to four equivalent K(1) and one Os(1) atom.
