The material described by Rb2S crystallizes in the hexagonal P6_3/mmc space group. There are two inequivalent Rb sites. In the first Rb site, Rb(1) is bonded to six equivalent S(1) atoms to form a mixture of distorted edge, face, and corner-sharing RbS6 octahedra. The corner-sharing octahedral tilt angles are 51°. In the second Rb site, Rb(2) is bonded in a distorted trigonal planar geometry to five equivalent S(1) atoms. S(1) is bonded in a 11-coordinate geometry to five equivalent Rb(2) and six equivalent Rb(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
