The structure described by 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. is represented by the Crystallographic Information File (CIF) [CIF]
