The material structure described by RbTmI3 crystallizes in the orthorhombic Pnma space group. Rb(1) is bonded in a 9-coordinate geometry to two equivalent I(1), three equivalent I(2), and four equivalent I(3) atoms. Tm(1) is bonded to one I(3), two equivalent I(2), and three equivalent I(1) atoms to form edge-sharing TmI6 octahedra. There are three inequivalent I sites. In the first I site, I(1) is bonded in a 5-coordinate geometry to two equivalent Rb(1) and three equivalent Tm(1) atoms. In the second I site, I(2) is bonded in a 5-coordinate geometry to three equivalent Rb(1) and two equivalent Tm(1) atoms. In the third I site, I(3) is bonded in a 5-coordinate geometry to four equivalent Rb(1) and one Tm(1) atom. is represented by the CIF file [CIF]
