Materials Data on EuH3CSO7 by Materials Project
EuCH3SO7 crystallizes in the tetragonal P4_1 space group. The structure is three-dimensional. Eu3+ is bonded in a 9-coordinate geometry to nine O2- atoms. There are a spread of Eu–O bond distances ranging from 2.43–2.75 Å. C4+ is bonded in a trigonal planar geometry to one H1+ and two O2- atoms. The C–H bond length is 1.10 Å. There is one shorter (1.27 Å) and one longer (1.28 Å) C–O bond length. There are three inequivalent H1+ sites. In the first H1+ site, H1+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 0.98 Å. In the second H1+ site, H1+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 0.99 Å. In the third H1+ site, H1+ is bonded in a single-bond geometry to one C4+ atom. S4+ is bonded in a tetrahedral geometry to four O2- atoms. There is three shorter (1.48 Å) and one longer (1.50 Å) S–O bond length. There are seven inequivalent O2- sites. In the first O2- site, O2- is bonded in a 1-coordinate geometry to one Eu3+ and one S4+ atom. In the second O2- site, O2- is bonded in a distorted bent 150 degrees geometry to one Eu3+ and one S4+ atom. In the third O2- site, O2- is bonded in a single-bond geometry to two equivalent Eu3+ and one C4+ atom. In the fourth O2- site, O2- is bonded in a distorted single-bond geometry to two equivalent Eu3+ and one C4+ atom. In the fifth O2- site, O2- is bonded in a water-like geometry to one Eu3+ and two H1+ atoms. In the sixth O2- site, O2- is bonded in a distorted bent 150 degrees geometry to one Eu3+ and one S4+ atom. In the seventh O2- site, O2- is bonded in a distorted bent 150 degrees geometry to one Eu3+ and one S4+ atom.
