Results for “NaSn5”

Materials Data on NaSn5 by Materials Project

NaSn5 crystallizes in the tetragonal P-42_1m space group. The structure is three-dimensional. Na is bonded in a 2-coordinate geometry to twelve Sn atoms. There are a spread of Na–Sn bond distances ranging from 3.11–3.77 Å. There are three inequivalent Sn sites. In the first Sn site, Sn is bonded in a 1-coordinate geometry to two equivalent Na and three Sn atoms. There are two shorter (2.92 Å) and one longer (2.96 Å) Sn–Sn bond lengths. In the second Sn site, Sn is bonded in a 8-coordinate geometry to four equivalent Na and four equivalent Sn atoms. In the third Sn site, Sn is bonded in a 7-coordinate geometry to two equivalent Na and five Sn atoms. All Sn–Sn bond lengths are 3.21 Å.
