Materials Data on TbSe3 by Materials Project
TbSe2Se crystallizes in the orthorhombic Cmmm space group. The structure is two-dimensional and consists of two selenium molecules and one TbSe2 sheet oriented in the (0, 0, 1) direction. In the TbSe2 sheet, Tb4+ is bonded in a distorted rectangular see-saw-like geometry to four equivalent Se+1.33- atoms. All Tb–Se bond lengths are 2.72 Å. Se+1.33- is bonded in a linear geometry to two equivalent Tb4+ atoms.
