Title: Materials Data on La4(DyS2)11 by Materials Project

Abstract

La4(DyS2)11 crystallizes in the monoclinic C2/m space group. The structure is three-dimensional. there are six inequivalent Dy3+ sites. In the first Dy3+ site, Dy3+ is bonded to seven S2- atoms to form distorted DyS7 pentagonal bipyramids that share corners with three DyS6 octahedra, edges with two equivalent DyS6 octahedra, and edges with four equivalent DyS7 pentagonal bipyramids. The corner-sharing octahedra tilt angles range from 40–50°. There are a spread of Dy–S bond distances ranging from 2.71–2.90 Å. In the second Dy3+ site, Dy3+ is bonded to six S2- atoms to form a mixture of corner and edge-sharing DyS6 octahedra. The corner-sharing octahedra tilt angles range from 49–59°. There are a spread of Dy–S bond distances ranging from 2.66–2.80 Å. In the third Dy3+ site, Dy3+ is bonded to six S2- atoms to form DyS6 octahedra that share corners with three equivalent DyS6 octahedra, corners with two equivalent DyS7 pentagonal bipyramids, and edges with four DyS6 octahedra. The corner-sharing octahedra tilt angles range from 51–63°. There are a spread of Dy–S bond distances ranging from 2.67–2.81 Å.
