Materials Data on RbSnBr3 by Materials Project
RbSnBr3 is (Cubic) Perovskite structured and crystallizes in the triclinic P1 space group. The structure is three-dimensional. Rb1+ is bonded in a 10-coordinate geometry to ten Br1- atoms. There are a spread of Rb–Br bond distances ranging from 3.83–4.25 Å. Sn2+ is bonded to six Br1- atoms to form corner-sharing SnBr6 octahedra. The corner-sharing octahedra tilt angles range from 1–5°. There are a spread of Sn–Br bond distances ranging from 2.91–2.96 Å. There are three inequivalent Br1- sites. In the first Br1- site, Br1- is bonded in a distorted linear geometry to four equivalent Rb1+ and two equivalent Sn2+ atoms. In the second Br1- site, Br1- is bonded in a 2-coordinate geometry to three equivalent Rb1+ and two equivalent Sn2+ atoms. In the third Br1- site, Br1- is bonded in a 2-coordinate geometry to three equivalent Rb1+ and two equivalent Sn2+ atoms.
