CsTmS2 is H-Phase structured and crystallizes in the hexagonal P6_3/mmc space group. Cs(1) is bonded in a 6-coordinate geometry to six equivalent S(1) atoms. Tm(1) is bonded to six equivalent S(1) atoms to form edge-sharing TmS6 octahedra. S(1) is bonded to three equivalent Cs(1) and three equivalent Tm(1) atoms to form a mixture of distorted edge, corner, and face-sharing SCs3Tm3 octahedra. The corner-sharing octahedral tilt angles range from 0-39°.
