CeNi2Al5 crystallizes in the orthorhombic Immm space group. Ce(1) is bonded in a 18-coordinate geometry to four equivalent Ni(1), two equivalent Al(1), and twelve equivalent Al(2) atoms. Ni(1) is bonded in a 9-coordinate geometry to two equivalent Ce(1), one Al(1), and six equivalent Al(2) atoms. There are two inequivalent Al sites. In the first Al site, Al(1) is bonded in a linear geometry to two equivalent Ce(1) and two equivalent Ni(1) atoms. In the second Al site, Al(2) is bonded in a distorted trigonal non-coplanar geometry to three equivalent Ce(1) and three equivalent Ni(1) atoms.
CeNi2Al5 crystallizes in the orthorhombic Immm space group. Ce(1) is bonded in a 18-coordinate geometry to four equivalent Ni(1), two equivalent Al(1), and twelve equivalent Al(2) atoms. All Ce(1)-Ni(1) bond lengths are 3.18 Å. Both Ce(1)-Al(1) bond lengths are 3.50 Å. There are eight shorter (3.31 Å) and four longer (3.51 Å) Ce(1)-Al(2) bond lengths. Ni(1) is bonded in a 9-coordinate geometry to two equivalent Ce(1), one Al(1), and six equivalent Al(2) atoms. The Ni(1)-Al(1) bond length is 2.27 Å. There are two shorter (2.38 Å) and four longer (2.51 Å) Ni(1)-Al(2) bond lengths. There are two inequivalent Al sites. In the first Al site, Al(1) is bonded in a linear geometry to two equivalent Ce(1) and two equivalent Ni(1) atoms. In the second Al site, Al(2) is bonded in a distorted trigonal non-coplanar geometry to three equivalent Ce(1) and three equivalent Ni(1) atoms.
