The material described by Rb3B12H12I crystallizes in the trigonal R-3m space group. Rb(1) is bonded in a 10-coordinate geometry to four equivalent H(1), four equivalent H(2), and two equivalent I(1) atoms. There are two inequivalent B sites. In the first B site, B(1) is bonded in a single-bond geometry to one H(1) atom. In the second B site, B(2) is bonded in a single-bond geometry to one H(2) atom. There are two inequivalent H sites. In the first H site, H(1) is bonded in a single-bond geometry to two equivalent Rb(1) and one B(1) atom. In the second H site, H(2) is bonded in a single-bond geometry to two equivalent Rb(1) and one B(2) atom. I(1) is bonded to six equivalent Rb(1) atoms to form corner-sharing IRb6 octahedra. The corner-sharing octahedra are not tilted. is represented by the Crystallographic Information File (CIF) [CIF]
