Materials Data on EuSO4 by Materials Project
EuSO4 crystallizes in the orthorhombic Pnma space group. The structure is three-dimensional. Eu2+ is bonded in a 10-coordinate geometry to ten O2- atoms. There are a spread of Eu–O bond distances ranging from 2.53–3.03 Å. S6+ is bonded in a tetrahedral geometry to four O2- atoms. There are a spread of S–O bond distances ranging from 1.47–1.51 Å. There are three inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted single-bond geometry to three equivalent Eu2+ and one S6+ atom. In the second O2- site, O2- is bonded in a distorted bent 150 degrees geometry to one Eu2+ and one S6+ atom. In the third O2- site, O2- is bonded in a distorted single-bond geometry to three equivalent Eu2+ and one S6+ atom.
