CsPtBr3 crystallizes in the orthorhombic Pnma space group. Cs(1) is bonded in a 6-coordinate geometry to one Br(3), two equivalent Br(1), and three equivalent Br(2) atoms. Pt(1) is bonded in a rectangular see-saw-like geometry to one Br(1), one Br(2), and two equivalent Br(3) atoms. There are three inequivalent Br sites. In the first Br site, Br(1) is bonded in a trigonal non-coplanar geometry to two equivalent Cs(1) and one Pt(1) atom. In the second Br site, Br(2) is bonded in a 4-coordinate geometry to three equivalent Cs(1) and one Pt(1) atom. In the third Br site, Br(3) is bonded in a distorted T-shaped geometry to one Cs(1) and two equivalent Pt(1) atoms.
