Materials Data on CeAl3Ni2 by Materials Project
CeNi2Al3 crystallizes in the hexagonal P6/mmm space group. The structure is three-dimensional. Ce is bonded in a 6-coordinate geometry to six equivalent Ni and twelve equivalent Al atoms. All Ce–Ni bond lengths are 3.05 Å. All Ce–Al bond lengths are 3.33 Å. Ni is bonded in a 9-coordinate geometry to three equivalent Ce and six equivalent Al atoms. All Ni–Al bond lengths are 2.53 Å. Al is bonded to four equivalent Ce and four equivalent Ni atoms to form a mixture of distorted edge, face, and corner-sharing AlCe4Ni4 cuboctahedra.
