CH3NH3PbBr3 is Orthorhombic Perovskite structured and crystallizes in the orthorhombic Pnma space group. The structure consists of four methylammonium molecules inside a PbBr3 framework. In the PbBr3 framework, Pb(1) is bonded to two equivalent Br(2) and four equivalent Br(1) atoms to form corner-sharing PbBr6 octahedra. The corner-sharing octahedral tilt angles range from 21-24°. There are two inequivalent Br sites. In the first Br site, Br(1) is bonded in a bent 150 degrees geometry to two equivalent Pb(1) atoms. In the second Br site, Br(2) is bonded in a bent 150 degrees geometry to two equivalent Pb(1) atoms.

In the PbBr3 framework, Pb(1) is bonded to two equivalent Br(2) and four equivalent Br(1) atoms to form corner-sharing PbBr6 octahedra. The corner-sharing octahedral tilt angles range from 21-24°. Both Pb(1)-Br(2) bond lengths are 3.10 Å. All Pb(1)-Br(1) bond lengths are 3.07 Å. There are two inequivalent Br sites. In the first Br site, Br(1) is bonded in a bent 150 degrees geometry to two equivalent Pb(1) atoms. In the second Br site, Br(2) is bonded in a bent 150 degrees geometry to two equivalent Pb(1) atoms.
