Abstract

CH3NH3PbBr3 crystallizes in the triclinic P1 space group. The structure is three-dimensional and consists of one methylammonium molecule and one Pb4C3H18(NBr4)3 framework. In the Pb4C3H18(NBr4)3 framework, there are four inequivalent Pb2+ sites. In the first Pb2+ site, Pb2+ is bonded to six Br1- atoms to form corner-sharing PbBr6 octahedra. The corner-sharing octahedra tilt angles range from 0–11°. There are a spread of Pb–Br bond distances ranging from 2.96–3.14 Å. In the second Pb2+ site, Pb2+ is bonded to six Br1- atoms to form corner-sharing PbBr6 octahedra. The corner-sharing octahedra tilt angles range from 0–11°. There are a spread of Pb–Br bond distances ranging from 2.96–3.14 Å. In the third Pb2+ site, Pb2+ is bonded to six Br1- atoms to form corner-sharing PbBr6 octahedra.
