KMoRu2 crystallizes in the cubic F-43m space group. K(1) is bonded in a distorted body-centered cubic geometry to four equivalent Mo(1), four equivalent Ru(2), and six equivalent Ru(1) atoms. Mo(1) is bonded to four equivalent K(1) and four equivalent Ru(1) atoms to form distorted MoK4Ru4 tetrahedra that share corners with eight equivalent Ru(2)K4Ru4 tetrahedra, edges with twelve equivalent Mo(1)K4Ru4 tetrahedra, and faces with six equivalent Ru(2)K4Ru4 tetrahedra. There are two inequivalent Ru sites. In the first Ru site, Ru(1) is bonded in a 14-coordinate geometry to six equivalent K(1), four equivalent Mo(1), and four equivalent Ru(2) atoms. In the second Ru site, Ru(2) is bonded to four equivalent K(1) and four equivalent Ru(1) atoms to form distorted RuK4Ru4 tetrahedra that share corners with eight equivalent Mo(1)K4Ru4 tetrahedra, edges with twelve equivalent Ru(2)K4Ru4 tetrahedra, and faces with six equivalent Mo(1)K4Ru4 tetrahedra.
