The material described by BaMg6Ti crystallizes in the hexagonal P-6m2 space group. Ba(1) is bonded to six equivalent Mg(1) and six equivalent Mg(2) atoms to form BaMg12 cuboctahedra that share corners with six equivalent Ba(1)Mg12 cuboctahedra, faces with two equivalent Ba(1)Mg12 cuboctahedra, and faces with six equivalent Ti(1)Mg12 cuboctahedra. There are two inequivalent Mg sites. In the first Mg site, Mg(1) is bonded in a 10-coordinate geometry to two equivalent Ba(1), two equivalent Mg(1), four equivalent Mg(2), and two equivalent Ti(1) atoms. In the second Mg site, Mg(2) is bonded in a 10-coordinate geometry to two equivalent Ba(1), two equivalent Mg(2), four equivalent Mg(1), and two equivalent Ti(1) atoms. Ti(1) is bonded to six equivalent Mg(1) and six equivalent Mg(2) atoms to form TiMg12 cuboctahedra that share corners with six equivalent Ti(1)Mg12 cuboctahedra, faces with two equivalent Ti(1)Mg12 cuboctahedra, and faces with six equivalent Ba(1)Mg12 cuboctahedra. is represented by the CIF card [CIF]
