K2OsCl6 crystallizes in the cubic Fm-3m space group. K(1) is bonded to twelve equivalent Cl(1) atoms to form KCl12 cuboctahedra that share corners with twelve equivalent K(1)Cl12 cuboctahedra, faces with six equivalent K(1)Cl12 cuboctahedra, and faces with four equivalent Os(1)Cl6 octahedra. Os(1) is bonded to six equivalent Cl(1) atoms to form OsCl6 octahedra that share faces with eight equivalent K(1)Cl12 cuboctahedra. Cl(1) is bonded to four equivalent K(1) and one Os(1) atom to form a mixture of distorted edge, face, and corner-sharing ClK4Os square pyramids.
