BaCe3 crystallizes in the hexagonal P6_3/mmc space group. Ba(1) is bonded to twelve equivalent Ce(1) atoms to form a mixture of distorted corner and face-sharing BaCe12 cuboctahedra. Ce(1) is bonded in a 10-coordinate geometry to four equivalent Ba(1) and six equivalent Ce(1) atoms.
BaCe3 crystallizes in the hexagonal P6_3/mmc space group. Ba(1) is bonded to twelve equivalent Ce(1) atoms to form a mixture of distorted corner and face-sharing BaCe12 cuboctahedra. There are six shorter (3.63 Å) and six longer (3.88 Å) Ba(1)-Ce(1) bond lengths. Ce(1) is bonded in a 10-coordinate geometry to four equivalent Ba(1) and six equivalent Ce(1) atoms. There are two shorter (2.89 Å) and four longer (3.40 Å) Ce(1)-Ce(1) bond lengths.
