Ba(TbS2)2 crystallizes in the orthorhombic Pnma space group. Ba(1) is bonded in a 8-coordinate geometry to two equivalent S(1), two equivalent S(2), two equivalent S(3), and two equivalent S(4) atoms. There are two inequivalent Tb sites. In the first Tb site, Tb(1) is bonded to one S(3), two equivalent S(1), and three equivalent S(4) atoms to form a mixture of corner and edge-sharing TbS6 octahedra. The corner-sharing octahedral tilt angles range from 48-61°. In the second Tb site, Tb(2) is bonded to one S(1), two equivalent S(3), and three equivalent S(2) atoms to form a mixture of corner and edge-sharing TbS6 octahedra. The corner-sharing octahedral tilt angles range from 48-61°. There are four inequivalent S sites. In the first S site, S(1) is bonded in a 5-coordinate geometry to two equivalent Ba(1), one Tb(2), and two equivalent Tb(1) atoms. In the second S site, S(2) is bonded to two equivalent Ba(1) and three equivalent Tb(2) atoms to form a mixture of corner and edge-sharing SBa2Tb3 square pyramids. In the third S site, S(3) is bonded to two equivalent Ba(1), one Tb(1), and two equivalent Tb(2) atoms to form a mixture of distorted corner and edge-sharing SBa2Tb3 trigonal bipyramids. In the fourth S site, S(4) is bonded to two equivalent Ba(1) and three equivalent Tb(1) atoms to form a mixture of distorted corner and edge-sharing SBa2Tb3 trigonal bipyramids.
