Materials Data on LaAgSn by Materials Project
LaAgSn crystallizes in the monoclinic C2/m space group. The structure is three-dimensional. La is bonded in a 12-coordinate geometry to six equivalent Ag and six equivalent Sn atoms. There are a spread of La–Ag bond distances ranging from 3.37–3.47 Å. There are a spread of La–Sn bond distances ranging from 3.35–3.76 Å. Ag is bonded in a 9-coordinate geometry to six equivalent La and three equivalent Ag atoms. All Ag–Ag bond lengths are 2.83 Å. Sn is bonded in a 9-coordinate geometry to six equivalent La and three equivalent Sn atoms. There are two shorter (2.89 Å) and one longer (2.93 Å) Sn–Sn bond lengths.
