Materials Data on CsTbS2 by Materials Project

CsTbS2 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 3.50 Å. Tb3+ is bonded to six equivalent S2- atoms to form edge-sharing TbS6 octahedra. All Tb–S bond lengths are 2.80 Å. S2- is bonded to three equivalent Cs1+ and three equivalent Tb3+ atoms to form a mixture of distorted edge and corner-sharing SCs3Tb3 octahedra. The corner-sharing octahedral tilt angles are 0°.

Materials Data on CsTbS2 by Materials Project

CsTbS2 is H-Phase structured and crystallizes in the hexagonal P6_3/mmc 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 3.48 Å. Tb3+ is bonded to six equivalent S2- atoms to form edge-sharing TbS6 octahedra. All Tb–S bond lengths are 2.80 Å. S2- is bonded to three equivalent Cs1+ and three equivalent Tb3+ atoms to form a mixture of distorted edge, corner, and face-sharing SCs3Tb3 octahedra. The corner-sharing octahedra tilt angles range from 0–40°.
