Materials Data on RbLuS2 by Materials Project
RbLuS2 is Caswellsilverite structured and crystallizes in the trigonal R-3m space group. The structure is three-dimensional. Rb1+ is bonded in a 6-coordinate geometry to six equivalent S2- atoms. All Rb–S bond lengths are 3.32 Å. Lu3+ is bonded to six equivalent S2- atoms to form edge-sharing LuS6 octahedra. All Lu–S bond lengths are 2.72 Å. S2- is bonded to three equivalent Rb1+ and three equivalent Lu3+ atoms to form a mixture of distorted corner and edge-sharing SRb3Lu3 octahedra. The corner-sharing octahedral tilt angles are 0°.
