The crystal structure described by RbMg6Ti crystallizes in the tetragonal P4/mmm space group. Rb(1) is bonded to four equivalent Mg(1) and eight equivalent Mg(2) atoms to form RbMg12 cuboctahedra that share corners with four equivalent Rb(1)Mg12 cuboctahedra, corners with eight equivalent Ti(1)Mg12 cuboctahedra, edges with eight equivalent Mg(1)Rb2Mg8Ti2 cuboctahedra, faces with two equivalent Rb(1)Mg12 cuboctahedra, faces with four equivalent Mg(1)Rb2Mg8Ti2 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 Rb(1), eight equivalent Mg(2), and two equivalent Ti(1) atoms to form MgRb2Mg8Ti2 cuboctahedra that share corners with twelve equivalent Mg(1)Rb2Mg8Ti2 cuboctahedra, edges with four equivalent Rb(1)Mg12 cuboctahedra, edges with four equivalent Ti(1)Mg12 cuboctahedra, faces with two equivalent Rb(1)Mg12 cuboctahedra, faces with two equivalent Ti(1)Mg12 cuboctahedra, and faces with six equivalent Mg(1)Rb2Mg8Ti2 cuboctahedra. In the second Mg site, Mg(2) is bonded in a 10-coordinate geometry to two equivalent Rb(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 Rb(1)Mg12 cuboctahedra, edges with eight equivalent Mg(1)Rb2Mg8Ti2 cuboctahedra, faces with two equivalent Ti(1)Mg12 cuboctahedra, faces with four equivalent Rb(1)Mg12 cuboctahedra, and faces with four equivalent Mg(1)Rb2Mg8Ti2 cuboctahedra. is represented by the CIF file [CIF]
