Materials Data on SmAgSn by Materials Project
SmAgSn crystallizes in the monoclinic C2/m space group. The structure is three-dimensional. Sm is bonded in a 12-coordinate geometry to six equivalent Ag and six equivalent Sn atoms. There are a spread of Sm–Ag bond distances ranging from 3.23–3.41 Å. There are a spread of Sm–Sn bond distances ranging from 3.25–3.76 Å. Ag is bonded in a 10-coordinate geometry to six equivalent Sm, three equivalent Ag, and one Sn atom. All Ag–Ag bond lengths are 2.83 Å. The Ag–Sn bond length is 3.22 Å. Sn is bonded in a 10-coordinate geometry to six equivalent Sm, one Ag, and three equivalent Sn atoms. All Sn–Sn bond lengths are 2.95 Å.
