Materials Data on BaU(SeO4)2 by Materials Project
BaU(SeO4)2 crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional. Ba2+ is bonded in a 8-coordinate geometry to eight O2- atoms. There are a spread of Ba–O bond distances ranging from 2.69–2.94 Å. U6+ is bonded in a 6-coordinate geometry to six O2- atoms. There are a spread of U–O bond distances ranging from 1.90–2.36 Å. There are two inequivalent Se4+ sites. In the first Se4+ site, Se4+ is bonded in a trigonal non-coplanar geometry to three O2- atoms. There are a spread of Se–O bond distances ranging from 1.69–1.79 Å. In the second Se4+ site, Se4+ is bonded in a water-like geometry to two O2- atoms. Both Se–O bond lengths are 1.76 Å. There are eight inequivalent O2- sites. In the first O2- site, O2- is bonded in a 3-coordinate geometry to one Ba2+, one U6+, and one Se4+ atom. In the second O2- site, O2- is bonded in a bent 120 degrees geometry to one U6+ and one Se4+ atom. In the third O2- site, O2- is bonded in a 3-coordinate geometry to two equivalent Ba2+ and one O2- atom. The O–O bond length is 1.36 Å. In the fourth O2- site, O2- is bonded in a 1-coordinate geometry to one Ba2+ and one Se4+ atom. In the fifth O2- site, O2- is bonded in a distorted trigonal planar geometry to one Ba2+, one U6+, and one Se4+ atom. In the sixth O2- site, O2- is bonded in a 3-coordinate geometry to one Ba2+, one U6+, and one Se4+ atom. In the seventh O2- site, O2- is bonded in a distorted single-bond geometry to one Ba2+ and one U6+ atom. In the eighth O2- site, O2- is bonded in a distorted single-bond geometry to one Ba2+ and one U6+ atom.
