Materials Data on Sn2IF2 by Materials Project
Sn2IF2 crystallizes in the orthorhombic C222_1 space group. The structure is two-dimensional and consists of two Sn2IF2 sheets oriented in the (0, 1, 0) direction. Sn is bonded in a 3-coordinate geometry to two equivalent I and three equivalent F atoms. There are one shorter (3.42 Å) and one longer (3.46 Å) Sn–I bond lengths. There are a spread of Sn–F bond distances ranging from 2.32–2.45 Å. I is bonded in a 4-coordinate geometry to four equivalent Sn atoms. F is bonded in a trigonal non-coplanar geometry to three equivalent Sn atoms.
