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.
