Materials Data on Sn2IF3 by Materials Project

Sn2IF3 crystallizes in the orthorhombic C222_1 space group. The structure is two-dimensional and consists of two Sn2IF3 sheets oriented in the (0, 1, 0) direction. Sn2+ is bonded in a 4-coordinate geometry to one I1- and four F1- atoms. The Sn–I bond length is 3.54 Å. There are a spread of Sn–F bond distances ranging from 2.17–2.45 Å. I1- is bonded in a 4-coordinate geometry to two equivalent Sn2+ and two equivalent F1- atoms. Both I–F bond lengths are 3.62 Å. There are two inequivalent F1- sites. In the first F1- site, F1- is bonded in a bent 120 degrees geometry to two equivalent Sn2+ atoms. In the second F1- site, F1- is bonded in a distorted trigonal planar geometry to three equivalent Sn2+ and one I1- atom.
