KMg6Ti crystallizes in the tetragonal P4/mmm space group. K(1) is bonded to four equivalent Mg(1) and eight equivalent Mg(2) atoms to form KMg12 cuboctahedra that share corners with four equivalent K(1)Mg12 cuboctahedra, corners with eight equivalent Ti(1)Mg12 cuboctahedra, edges with eight equivalent Mg(1)K2Mg8Ti2 cuboctahedra, faces with two equivalent K(1)Mg12 cuboctahedra, faces with four equivalent Mg(1)K2Mg8Ti2 cuboctahedra, and faces with four equivalent Ti(1)Mg12 cuboctahedra. There are two inequivalent Mg sites. In the first Mg site, Mg(1) is bonded to two equivalent K(1), eight equivalent Mg(2), and two equivalent Ti(1) atoms to form distorted MgK2Mg8Ti2 cuboctahedra that share corners with twelve equivalent Mg(1)K2Mg8Ti2 cuboctahedra, edges with four equivalent K(1)Mg12 cuboctahedra, edges with four equivalent Ti(1)Mg12 cuboctahedra, faces with two equivalent K(1)Mg12 cuboctahedra, faces with two equivalent Ti(1)Mg12 cuboctahedra, and faces with six equivalent Mg(1)K2Mg8Ti2 cuboctahedra. In the second Mg site, Mg(2) is bonded in a 10-coordinate geometry to two equivalent K(1), two equivalent Mg(2), four equivalent Mg(1), and two equivalent Ti(1) atoms. Ti(1) is bonded to four equivalent Mg(1) and eight equivalent Mg(2) atoms to form TiMg12 cuboctahedra that share corners with four equivalent Ti(1)Mg12 cuboctahedra, corners with eight equivalent K(1)Mg12 cuboctahedra, edges with eight equivalent Mg(1)K2Mg8Ti2 cuboctahedra, faces with two equivalent Ti(1)Mg12 cuboctahedra, faces with four equivalent K(1)Mg12 cuboctahedra, and faces with four equivalent Mg(1)K2Mg8Ti2 cuboctahedra.
