In2S3 crystallizes in the orthorhombic Imm2 space group. In(1) is bonded to one S(2) and three equivalent S(1) atoms to form corner-sharing InS4 tetrahedra. There are two inequivalent S sites. In the first S site, S(1) is bonded in a trigonal non-coplanar geometry to three equivalent In(1) atoms. In the second S site, S(2) is bonded in a water-like geometry to two equivalent In(1) atoms.
In2S3 crystallizes in the orthorhombic Imm2 space group. In(1) is bonded to one S(2) and three equivalent S(1) atoms to form corner-sharing InS4 tetrahedra. The In(1)-S(2) bond length is 2.39 Å. There is one shorter (2.51 Å) and two longer (2.52 Å) In(1)-S(1) bond lengths. There are two inequivalent S sites. In the first S site, S(1) is bonded in a trigonal non-coplanar geometry to three equivalent In(1) atoms. In the second S site, S(2) is bonded in a water-like geometry to two equivalent In(1) atoms.
