Materials Data on YbGdS3 by Materials Project
YbGdS3 crystallizes in the orthorhombic Pnma space group. The structure is three-dimensional. Yb3+ is bonded in a 8-coordinate geometry to eight S2- atoms. There are a spread of Yb–S bond distances ranging from 2.82–3.24 Å. Gd3+ is bonded to seven S2- atoms to form distorted edge-sharing GdS7 pentagonal bipyramids. There are a spread of Gd–S bond distances ranging from 2.73–2.89 Å. There are three inequivalent S2- sites. In the first S2- site, S2- is bonded in a 5-coordinate geometry to two equivalent Yb3+ and three equivalent Gd3+ atoms. In the second S2- site, S2- is bonded in a 5-coordinate geometry to four equivalent Yb3+ and one Gd3+ atom. In the third S2- site, S2- is bonded in a 5-coordinate geometry to two equivalent Yb3+ and three equivalent Gd3+ atoms.
