Title: Materials Data on NaSn2 by Materials Project

Abstract

NaSn2 crystallizes in the monoclinic C2/m space group. The structure is three-dimensional. there are four inequivalent Na sites. In the first Na site, Na is bonded in a 10-coordinate geometry to eight Sn atoms. There are a spread of Na–Sn bond distances ranging from 3.28–3.73 Å. In the second Na site, Na is bonded in a 10-coordinate geometry to eight Sn atoms. There are a spread of Na–Sn bond distances ranging from 3.26–3.63 Å. In the third Na site, Na is bonded to four Sn atoms to form edge-sharing NaSn4 tetrahedra. There are two shorter (3.16 Å) and two longer (3.18 Å) Na–Sn bond lengths. In the fourth Na site, Na is bonded in a 6-coordinate geometry to six Sn atoms. There are a spread of Na–Sn bond distances ranging from 3.44–3.54 Å. There are five inequivalent Sn sites. In the first Sn site, Sn is bonded in a 7-coordinate geometry to three Na and four Sn atoms. There are a spread of Sn–Sn bond distances ranging from 2.93–3.00 Å. In the second Sn site, Sn is bonded in a 7-coordinate geometry to three Na and four Sn atoms. There are a spread of Sn–Sn bond distances ranging from 2.93–2.98more » Å. In the third Sn site, Sn is bonded in a 6-coordinate geometry to three Na and three Sn atoms. The Sn–Sn bond length is 2.88 Å. In the fourth Sn site, Sn is bonded in a 6-coordinate geometry to three Na and three Sn atoms. In the fifth Sn site, Sn is bonded in a 7-coordinate geometry to four Na and three Sn atoms. The Sn–Sn bond length is 3.02 Å.« less
