Materials Data on Sm2InAu2 by Materials Project
Sm2Au2In 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 In atoms. There are two shorter (3.00 Å) and four longer (3.11 Å) Sm–Au bond lengths. All Sm–In bond lengths are 3.56 Å. Au is bonded in a 9-coordinate geometry to six equivalent Sm, one Au, and two equivalent In atoms. The Au–Au bond length is 2.88 Å. Both Au–In bond lengths are 3.20 Å. In is bonded to eight equivalent Sm and four equivalent Au atoms to form a mixture of face and corner-sharing InSm8Au4 cuboctahedra.
