The crystal structure described by KOs2O6 crystallizes in the triclinic P-1 space group. K(1) is bonded in a 11-coordinate geometry to one O(2), one O(6), two equivalent O(1), two equivalent O(4), two equivalent O(5), and three equivalent O(3) atoms. There are two inequivalent Os sites. In the first Os site, Os(1) is bonded to one O(2), one O(3), one O(5), one O(6), and two equivalent O(4) atoms to form a mixture of corner and edge-sharing OsO6 octahedra. The corner-sharing octahedral tilt angles range from 39-46°. In the second Os site, Os(2) is bonded to one O(2), one O(3), one O(5), one O(6), and two equivalent O(1) atoms to form a mixture of corner and edge-sharing OsO6 octahedra. The corner-sharing octahedral tilt angles range from 39-46°. There are six inequivalent O sites. In the first O site, O(1) is bonded in a 4-coordinate geometry to two equivalent K(1) and two equivalent Os(2) atoms. In the second O site, O(2) is bonded in a 3-coordinate geometry to one K(1), one Os(1), and one Os(2) atom. In the third O site, O(3) is bonded in a 2-coordinate geometry to three equivalent K(1), one Os(1), and one Os(2) atom. In the fourth O site, O(4) is bonded in a 4-coordinate geometry to two equivalent K(1) and two equivalent Os(1) atoms. In the fifth O site, O(5) is bonded in a 2-coordinate geometry to two equivalent K(1), one Os(1), and one Os(2) atom. In the sixth O site, O(6) is bonded in a distorted bent 150 degrees geometry to one K(1), one Os(1), and one Os(2) atom. is represented by the Crystallographic Information File (CIF) [CIF]
