Materials Data on SmGeAu by Materials Project
SmAuGe crystallizes in the hexagonal P6_3mc space group. The structure is three-dimensional. Sm is bonded in a 12-coordinate geometry to six equivalent Au and six equivalent Ge atoms. There are three shorter (3.12 Å) and three longer (3.34 Å) Sm–Au bond lengths. There are three shorter (3.06 Å) and three longer (3.40 Å) Sm–Ge bond lengths. Au is bonded in a 9-coordinate geometry to six equivalent Sm and three equivalent Ge atoms. All Au–Ge bond lengths are 2.64 Å. Ge is bonded in a 3-coordinate geometry to six equivalent Sm and three equivalent Au atoms.
