Materials Data on Gd2S2O by Materials Project
Gd2S2O crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional. there are two inequivalent Gd3+ sites. In the first Gd3+ site, Gd3+ is bonded in a 1-coordinate geometry to six S2- and one O2- atom. There are a spread of Gd–S bond distances ranging from 2.78–2.96 Å. The Gd–O bond length is 2.29 Å. In the second Gd3+ site, Gd3+ is bonded in a 7-coordinate geometry to four S2- and three equivalent O2- atoms. There are a spread of Gd–S bond distances ranging from 2.81–3.17 Å. There are a spread of Gd–O bond distances ranging from 2.29–2.32 Å. There are two inequivalent S2- sites. In the first S2- site, S2- is bonded in a 5-coordinate geometry to five Gd3+ atoms. In the second S2- site, S2- is bonded in a 5-coordinate geometry to five Gd3+ atoms. O2- is bonded to four Gd3+ atoms to form a mixture of edge and corner-sharing OGd4 tetrahedra.
