Materials Data on LaCdAu by Materials Project

LaAuCd crystallizes in the hexagonal P-62m space group. The structure is three-dimensional. La is bonded in a 11-coordinate geometry to five Au and six equivalent Cd atoms. There are four shorter (3.20 Å) and one longer (3.26 Å) La–Au bond lengths. There are two shorter (3.44 Å) and four longer (3.54 Å) La–Cd bond lengths. There are two inequivalent Au sites. In the first Au site, Au is bonded in a 9-coordinate geometry to three equivalent La and six equivalent Cd atoms. All Au–Cd bond lengths are 2.90 Å. In the second Au site, Au is bonded in a 9-coordinate geometry to six equivalent La and three equivalent Cd atoms. All Au–Cd bond lengths are 3.05 Å. Cd is bonded in a 4-coordinate geometry to six equivalent La and four Au atoms.

Materials Data on La2CdAu2 by Materials Project

La2Au2Cd crystallizes in the tetragonal P4/mbm space group. The structure is three-dimensional. La is bonded in a 6-coordinate geometry to six equivalent Au and four equivalent Cd atoms. There are two shorter (3.06 Å) and four longer (3.20 Å) La–Au bond lengths. All La–Cd bond lengths are 3.65 Å. Au is bonded in a 9-coordinate geometry to six equivalent La, one Au, and two equivalent Cd atoms. The Au–Au bond length is 3.00 Å. Both Au–Cd bond lengths are 3.29 Å. Cd is bonded to eight equivalent La and four equivalent Au atoms to form a mixture of corner and face-sharing CdLa8Au4 cuboctahedra.
