Materials Data on U2S5 by Materials Project

U2S5 crystallizes in the orthorhombic Pbcn space group. The structure is three-dimensional. U5+ is bonded in a 10-coordinate geometry to ten S2- atoms. There are a spread of U–S bond distances ranging from 2.79–2.99 Å. There are three inequivalent S2- sites. In the first S2- site, S2- is bonded in a 4-coordinate geometry to four equivalent U5+ atoms. In the second S2- site, S2- is bonded in a 6-coordinate geometry to four equivalent U5+ and one S2- atom. The S–S bond length is 2.22 Å. In the third S2- site, S2- is bonded in a 4-coordinate geometry to four equivalent U5+ atoms.
