CeNi2Al3 crystallizes in the hexagonal P6/mmm space group. Ce(1) is bonded in a 18-coordinate geometry to six equivalent Ni(1) and twelve equivalent Al(1) atoms. Ni(1) is bonded in a 9-coordinate geometry to three equivalent Ce(1) and six equivalent Al(1) atoms. Al(1) is bonded to four equivalent Ce(1) and four equivalent Ni(1) atoms to form a mixture of distorted corner, face, and edge-sharing AlCe4Ni4 cuboctahedra.
