TbBS3 crystallizes in the orthorhombic Pna2_1 space group. Tb(1) is bonded in a 8-coordinate geometry to two equivalent S(3), three equivalent S(1), and three equivalent S(2) atoms. B(1) is bonded in a trigonal planar geometry to one S(1), one S(2), and one S(3) atom. There are three inequivalent S sites. In the first S site, S(1) is bonded in a 4-coordinate geometry to three equivalent Tb(1) and one B(1) atom. In the second S site, S(2) is bonded in a 4-coordinate geometry to three equivalent Tb(1) and one B(1) atom. In the third S site, S(3) is bonded in a 3-coordinate geometry to two equivalent Tb(1) and one B(1) atom.
