Materials Data on Sm2SCl4 by Materials Project
Sm2SCl4 crystallizes in the monoclinic C2/c space group. The structure is three-dimensional. Sm3+ is bonded in a 8-coordinate geometry to two equivalent S2- and six Cl1- atoms. Both Sm–S bond lengths are 2.80 Å. There are a spread of Sm–Cl bond distances ranging from 2.79–3.23 Å. S2- is bonded to four equivalent Sm3+ atoms to form distorted edge-sharing SSm4 tetrahedra. There are two inequivalent Cl1- sites. In the first Cl1- site, Cl1- is bonded in a 2-coordinate geometry to three equivalent Sm3+ atoms. In the second Cl1- site, Cl1- is bonded in a 3-coordinate geometry to three equivalent Sm3+ atoms.
