Materials Data on Dy2SnS3 by Materials Project

Abstract

Dy2SnS3 crystallizes in the monoclinic Cc space group. The structure is three-dimensional. there are two inequivalent Dy sites. In the first Dy site, Dy is bonded in a 4-coordinate geometry to four S atoms. There are a spread of Dy–S bond distances ranging from 2.64–2.69 Å. In the second Dy site, Dy is bonded in a distorted rectangular see-saw-like geometry to four S atoms. There are a spread of Dy–S bond distances ranging from 2.65–2.69 Å. Sn is bonded in a 2-coordinate geometry to two S atoms. There are one shorter (2.56 Å) and one longer (2.81 Å) Sn–S bond lengths. There are three inequivalent S sites. In the first S site, S is bonded in a distorted T-shaped geometry to two Dy and one Sn atom. In the second S site, S is bonded in a rectangular see-saw-like geometry to three Dy and one Sn atom. In the third S site, S is bonded in a 3-coordinate geometry to three Dy atoms.
