CeMg crystallizes in the hexagonal P6_3/mmc space group. Mg(1) is bonded to five equivalent Ce(1) atoms to form a mixture of corner and edge-sharing MgCe5 trigonal bipyramids. Ce(1) is bonded to five equivalent Mg(1) atoms to form a mixture of corner and edge-sharing CeMg5 trigonal bipyramids.
CeMg crystallizes in the hexagonal P6_3/mmc space group. Mg(1) is bonded to five equivalent Ce(1) atoms to form a mixture of corner and edge-sharing MgCe5 trigonal bipyramids. There are three shorter (3.21 Å) and two longer (3.23 Å) Mg(1)-Ce(1) bond lengths. Ce(1) is bonded to five equivalent Mg(1) atoms to form a mixture of corner and edge-sharing CeMg5 trigonal bipyramids.
