The material structure described by RbCu2I3 crystallizes in the orthorhombic Pnma space group. Rb(1) is bonded in a 7-coordinate geometry to two equivalent I(2), two equivalent I(3), and three equivalent I(1) atoms. Cu(1) is bonded to one I(1), one I(3), and two equivalent I(2) atoms to form a mixture of distorted corner and edge-sharing CuI4 tetrahedra. There are three inequivalent I sites. In the first I site, I(1) is bonded in a 5-coordinate geometry to three equivalent Rb(1) and two equivalent Cu(1) atoms. In the second I site, I(2) is bonded in a 6-coordinate geometry to two equivalent Rb(1) and four equivalent Cu(1) atoms. In the third I site, I(3) is bonded in a distorted rectangular see-saw-like geometry to two equivalent Rb(1) and two equivalent Cu(1) atoms. is represented by the CIF card [CIF]
