TbMgCo4 is Hexagonal Laves-derived structured and crystallizes in the cubic F-43m space group. Mg(1) is bonded in a 16-coordinate geometry to four equivalent Tb(1) and twelve equivalent Co(1) atoms. Tb(1) is bonded in a 16-coordinate geometry to four equivalent Mg(1) and twelve equivalent Co(1) atoms. Co(1) is bonded to three equivalent Mg(1), three equivalent Tb(1), and six equivalent Co(1) atoms to form a mixture of face, edge, and corner-sharing CoTb3Mg3Co6 cuboctahedra.
TbMgCo4 is Hexagonal Laves-derived structured and crystallizes in the cubic F-43m space group. Mg(1) is bonded in a 16-coordinate geometry to four equivalent Tb(1) and twelve equivalent Co(1) atoms. All Mg(1)-Tb(1) bond lengths are 3.03 Å. All Mg(1)-Co(1) bond lengths are 2.91 Å. Tb(1) is bonded in a 16-coordinate geometry to four equivalent Mg(1) and twelve equivalent Co(1) atoms. All Tb(1)-Co(1) bond lengths are 2.91 Å. Co(1) is bonded to three equivalent Mg(1), three equivalent Tb(1), and six equivalent Co(1) atoms to form a mixture of face, edge, and corner-sharing CoTb3Mg3Co6 cuboctahedra. There are three shorter (2.47 Å) and three longer (2.48 Å) Co(1)-Co(1) bond lengths.
