Materials Data on RbPbBr3 by Materials Project

Abstract

RbPbBr3 is (Cubic) Perovskite structured and crystallizes in the triclinic P1 space group. The structure is three-dimensional. Rb1+ is bonded in a 12-coordinate geometry to twelve Br1- atoms. There are a spread of Rb–Br bond distances ranging from 4.13–4.33 Å. Pb2+ is bonded to six Br1- atoms to form corner-sharing PbBr6 octahedra. The corner-sharing octahedra tilt angles range from 1–5°. There are three shorter (2.99 Å) and three longer (3.00 Å) Pb–Br bond lengths. 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 Pb2+ atoms. In the second Br1- site, Br1- is bonded in a distorted linear geometry to four equivalent Rb1+ and two equivalent Pb2+ atoms. In the third Br1- site, Br1- is bonded in a distorted linear geometry to four equivalent Rb1+ and two equivalent Pb2+ atoms.
