Materials Data on CsSmS2 by Materials Project
CsSmS2 is Caswellsilverite structured and crystallizes in the trigonal R-3m space group. The structure is three-dimensional. Cs1+ is bonded in a 6-coordinate geometry to six equivalent S2- atoms. All Cs–S bond lengths are 3.52 Å. Sm3+ is bonded to six equivalent S2- atoms to form edge-sharing SmS6 octahedra. All Sm–S bond lengths are 2.85 Å. S2- is bonded to three equivalent Cs1+ and three equivalent Sm3+ atoms to form a mixture of distorted edge and corner-sharing SCs3Sm3 octahedra. The corner-sharing octahedral tilt angles are 0°.
