Materials Data on SnF2 by Materials Project
SnF2 crystallizes in the monoclinic C2/c space group. The structure is three-dimensional. there are two inequivalent Sn2+ sites. In the first Sn2+ site, Sn2+ is bonded to five F1- atoms to form distorted corner-sharing SnF5 square pyramids. There are a spread of Sn–F bond distances ranging from 2.10–2.52 Å. In the second Sn2+ site, Sn2+ is bonded in a 4-coordinate geometry to four F1- atoms. There are a spread of Sn–F bond distances ranging from 2.13–2.67 Å. There are four inequivalent F1- sites. In the first F1- site, F1- is bonded in a bent 120 degrees geometry to two Sn2+ atoms. In the second F1- site, F1- is bonded in a 3-coordinate geometry to three Sn2+ atoms. In the third F1- site, F1- is bonded in a distorted bent 150 degrees geometry to two equivalent Sn2+ atoms. In the fourth F1- site, F1- is bonded in a linear geometry to two Sn2+ atoms.
