Materials Data on Ce(AlPd)2 by Materials Project
CePd2Al2 crystallizes in the tetragonal P4/nmm space group. The structure is three-dimensional. Ce is bonded in a 12-coordinate geometry to eight Pd and eight Al atoms. There are four shorter (3.28 Å) and four longer (3.38 Å) Ce–Pd bond lengths. There are four shorter (3.31 Å) and four longer (3.37 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 four equivalent Ce and five Al atoms. There are one shorter (2.51 Å) and four longer (2.56 Å) Pd–Al bond lengths. In the second Pd site, Pd is bonded to four equivalent Ce and four equivalent Al atoms to form distorted PdCe4Al4 tetrahedra that share corners with twelve equivalent AlCe4Pd4 tetrahedra, edges with two equivalent AlCe4Pd4 tetrahedra, edges with four equivalent PdCe4Al4 tetrahedra, and faces with four equivalent PdCe4Al4 tetrahedra. All Pd–Al bond lengths are 2.52 Å. There are two inequivalent Al sites. In the first Al site, Al is bonded in a 5-coordinate geometry to four equivalent Ce and five Pd atoms. In the second Al site, Al is bonded to four equivalent Ce and four equivalent Pd atoms to form distorted AlCe4Pd4 tetrahedra that share corners with twelve equivalent PdCe4Al4 tetrahedra, edges with two equivalent PdCe4Al4 tetrahedra, edges with four equivalent AlCe4Pd4 tetrahedra, and faces with four equivalent AlCe4Pd4 tetrahedra.
