Materials Data on Ce(GaPd)2 by Materials Project
Ce(PdGa)2 crystallizes in the tetragonal P4/nmm space group. The structure is three-dimensional. Ce is bonded in a 4-coordinate geometry to eight Pd and eight Ga atoms. There are four shorter (3.27 Å) and four longer (3.41 Å) Ce–Pd bond lengths. There are four shorter (3.32 Å) and four longer (3.34 Å) Ce–Ga bond lengths. There are two inequivalent Pd sites. In the first Pd site, Pd is bonded to four equivalent Ce and four equivalent Ga atoms to form distorted PdCe4Ga4 tetrahedra that share corners with twelve equivalent GaCe4Pd4 tetrahedra, edges with two equivalent GaCe4Pd4 tetrahedra, edges with four equivalent PdCe4Ga4 tetrahedra, and faces with four equivalent PdCe4Ga4 tetrahedra. All Pd–Ga bond lengths are 2.54 Å. In the second Pd site, Pd is bonded in a 9-coordinate geometry to four equivalent Ce and five Ga atoms. There are one shorter (2.49 Å) and four longer (2.55 Å) Pd–Ga bond lengths. There are two inequivalent Ga sites. In the first Ga site, Ga is bonded to four equivalent Ce and four equivalent Pd atoms to form distorted GaCe4Pd4 tetrahedra that share corners with twelve equivalent PdCe4Ga4 tetrahedra, edges with two equivalent PdCe4Ga4 tetrahedra, edges with four equivalent GaCe4Pd4 tetrahedra, and faces with four equivalent GaCe4Pd4 tetrahedra. In the second Ga site, Ga is bonded in a 9-coordinate geometry to four equivalent Ce and five Pd atoms.
