Materials Data on CeAlPd by Materials Project

CePdAl crystallizes in the hexagonal P-62m space group. The structure is three-dimensional. Ce is bonded in a 5-coordinate geometry to five Pd and six equivalent Al atoms. There are four shorter (3.00 Å) and one longer (3.03 Å) Ce–Pd bond lengths. There are two shorter (3.24 Å) and four longer (3.36 Å) Ce–Al bond lengths. There are two inequivalent Pd sites. In the first Pd site, Pd is bonded in a 9-coordinate geometry to three equivalent Ce and six equivalent Al atoms. All Pd–Al bond lengths are 2.68 Å. In the second Pd site, Pd is bonded in a 9-coordinate geometry to six equivalent Ce and three equivalent Al atoms. All Pd–Al bond lengths are 2.82 Å. Al is bonded in a 4-coordinate geometry to six equivalent Ce and four Pd atoms.

Materials Data on CeAl2Pd5 by Materials Project

CePd5Al2 crystallizes in the tetragonal I4/mmm space group. The structure is three-dimensional. Ce is bonded to twelve Pd atoms to form a mixture of corner and face-sharing CePd12 cuboctahedra. There are four shorter (2.97 Å) and eight longer (3.02 Å) Ce–Pd bond lengths. There are two inequivalent Pd sites. In the first Pd site, Pd is bonded in a distorted square co-planar geometry to four equivalent Ce atoms. In the second Pd site, Pd is bonded in a 6-coordinate geometry to two equivalent Ce and four equivalent Al atoms. There are two shorter (2.59 Å) and two longer (2.65 Å) Pd–Al bond lengths. Al is bonded in a body-centered cubic geometry to eight equivalent Pd atoms.
