Materials Data on CsCeS2 by Materials Project
CsCeS2 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 3.54 Å. Ce3+ is bonded to six equivalent S2- atoms to form edge-sharing CeS6 octahedra. All Ce–S bond lengths are 2.89 Å. S2- is bonded to three equivalent Cs1+ and three equivalent Ce3+ atoms to form a mixture of distorted edge and corner-sharing SCs3Ce3 octahedra. The corner-sharing octahedral tilt angles are 0°.
