TbS2 crystallizes in the monoclinic P2_1/c space group. Tb(1) is bonded in a 9-coordinate geometry to four equivalent S(2) and five equivalent S(1) atoms. There are two inequivalent S sites. In the first S site, S(2) is bonded in a 5-coordinate geometry to four equivalent Tb(1) and one S(2) atom. In the second S site, S(1) is bonded to five equivalent Tb(1) atoms to form a mixture of distorted edge and corner-sharing STb5 trigonal bipyramids.
