Sm2SCl4 is Zircon-like structured and crystallizes in the monoclinic C2/c space group. Sm(1) is bonded in a 8-coordinate geometry to two equivalent S(1), three equivalent Cl(1), and three equivalent Cl(2) atoms. S(1) is bonded to four equivalent Sm(1) atoms to form edge-sharing SSm4 tetrahedra. There are two inequivalent Cl sites. In the first Cl site, Cl(1) is bonded in a 3-coordinate geometry to three equivalent Sm(1) atoms. In the second Cl site, Cl(2) is bonded in a distorted trigonal non-coplanar geometry to three equivalent Sm(1) atoms.
Sm2SCl4 is Zircon-like structured and crystallizes in the monoclinic C2/c space group. Sm(1) is bonded in a 8-coordinate geometry to two equivalent S(1), three equivalent Cl(1), and three equivalent Cl(2) atoms. There is one shorter (2.78 Å) and one longer (2.79 Å) Sm(1)-S(1) bond length. There are a spread of Sm(1)-Cl(1) bond distances ranging from 2.77-3.21 Å. There are a spread of Sm(1)-Cl(2) bond distances ranging from 2.79-2.96 Å. S(1) is bonded to four equivalent Sm(1) atoms to form edge-sharing SSm4 tetrahedra. There are two inequivalent Cl sites.
