Ta2InS4 crystallizes in the orthorhombic Imm2 space group. Ta(1) is bonded to three equivalent S(1) and three equivalent S(2) atoms to form distorted edge-sharing TaS6 pentagonal pyramids. In(1) is bonded in a 2-coordinate geometry to two equivalent S(2) atoms. There are two inequivalent S sites. In the first S site, S(1) is bonded in a 3-coordinate geometry to three equivalent Ta(1) atoms. In the second S site, S(2) is bonded in a distorted rectangular see-saw-like geometry to three equivalent Ta(1) and one In(1) atom.
Ta2InS4 crystallizes in the orthorhombic Imm2 space group. Ta(1) is bonded to three equivalent S(1) and three equivalent S(2) atoms to form distorted edge-sharing TaS6 pentagonal pyramids. There is one shorter (2.47 Å) and two longer (2.48 Å) Ta(1)-S(1) bond lengths. There are two shorter (2.47 Å) and one longer (2.48 Å) Ta(1)-S(2) bond length. In(1) is bonded in a 2-coordinate geometry to two equivalent S(2) atoms. Both In(1)-S(2) bond lengths are 3.02 Å. There are two inequivalent S sites. In the first S site, S(1) is bonded in a 3-coordinate geometry to three equivalent Ta(1) atoms. In the second S site, S(2) is bonded in a distorted rectangular see-saw-like geometry to three equivalent Ta(1) and one In(1) atom.
