Materials Data on CsSnF3 by Materials Project
CsSnF3 crystallizes in the trigonal R3c space group. The structure is three-dimensional. Cs1+ is bonded in a 6-coordinate geometry to six equivalent F1- atoms. There are three shorter (3.07 Å) and three longer (3.20 Å) Cs–F bond lengths. Sn2+ is bonded in a distorted T-shaped geometry to three equivalent F1- atoms. All Sn–F bond lengths are 2.12 Å. F1- is bonded in a 1-coordinate geometry to two equivalent Cs1+ and one Sn2+ atom.
