Materials Data on SnF4 by Materials Project

SnF4 crystallizes in the tetragonal I4/mmm space group. The structure is two-dimensional and consists of two SnF4 sheets oriented in the (0, 0, 1) direction. Sn4+ is bonded to six F1- atoms to form corner-sharing SnF6 octahedra. The corner-sharing octahedral tilt angles are 0°. There is two shorter (1.91 Å) and four longer (2.08 Å) Sn–F bond length. There are two inequivalent F1- sites. In the first F1- site, F1- is bonded in a single-bond geometry to one Sn4+ atom. In the second F1- site, F1- is bonded in a linear geometry to two equivalent Sn4+ atoms.

Materials Data on Sn(NF)2 by Materials Project

Sn(NF)2 crystallizes in the monoclinic C2/m space group. The structure is two-dimensional and consists of two Sn(NF)2 sheets oriented in the (0, 1, 0) direction. Sn4+ is bonded to four equivalent F1- atoms to form distorted edge-sharing SnF4 hexagonal bipyramids. All Sn–F bond lengths are 2.35 Å. N1- is bonded in a 2-coordinate geometry to one N1- and one F1- atom. The N–N bond length is 1.12 Å. The N–F bond length is 2.55 Å. F1- is bonded in a 3-coordinate geometry to two equivalent Sn4+ and one N1- atom.
