Materials Data on KSn2Br5 by Materials Project
Abstract
KSn2Br5 crystallizes in the tetragonal I4/mcm space group. The structure is three-dimensional. K1+ is bonded in a 10-coordinate geometry to ten Br1- atoms. There are eight shorter (3.62 Å) and two longer (3.76 Å) K–Br bond lengths. Sn2+ is bonded in a 4-coordinate geometry to four Br1- atoms. There are two shorter (2.78 Å) and two longer (3.12 Å) Sn–Br bond lengths. There are two inequivalent Br1- sites. In the first Br1- site, Br1- is bonded to two equivalent K1+ and four equivalent Sn2+ atoms to form corner-sharing BrK2Sn4 octahedra. The corner-sharing octahedra tilt angles range from 0–33°. In the second Br1- site, Br1- is bonded in a distorted trigonal non-coplanar geometry to two equivalent K1+ and one Sn2+ atom.
