Materials Data on TbS3 by Materials Project
TbS2S crystallizes in the orthorhombic Cmmm space group. The structure is two-dimensional and consists of two hydrogen sulfide molecules and one TbS2 sheet oriented in the (0, 0, 1) direction. In the TbS2 sheet, Tb4+ is bonded in a distorted rectangular see-saw-like geometry to four equivalent S+1.33- atoms. All Tb–S bond lengths are 2.61 Å. S+1.33- is bonded in a linear geometry to two equivalent Tb4+ atoms.
