Materials Data on Sm2CdAu2 by Materials Project
Sm2Au2Cd crystallizes in the tetragonal P4/mbm space group. The structure is three-dimensional. Sm is bonded in a 6-coordinate geometry to six equivalent Au and four equivalent Cd atoms. There are two shorter (2.99 Å) and four longer (3.10 Å) Sm–Au bond lengths. All Sm–Cd bond lengths are 3.57 Å. Au is bonded in a 9-coordinate geometry to six equivalent Sm and two equivalent Cd atoms. Both Au–Cd bond lengths are 3.21 Å. Cd is bonded to eight equivalent Sm and four equivalent Au atoms to form a mixture of distorted corner and face-sharing CdSm8Au4 cuboctahedra.
