Title: Materials Data on KUI3O11 by Materials Project

Abstract

KUO11I3 crystallizes in the orthorhombic Pbca space group. The structure is two-dimensional and consists of two KUO11I3 sheets oriented in the (0, 0, 1) direction. K1+ is bonded in a 8-coordinate geometry to eight O2- atoms. There are a spread of K–O bond distances ranging from 2.66–3.29 Å. U6+ is bonded in a distorted pentagonal bipyramidal geometry to seven O2- atoms. There are a spread of U–O bond distances ranging from 1.82–2.44 Å. There are eleven inequivalent O2- sites. In the first O2- site, O2- is bonded in a single-bond geometry to one U6+ atom. In the second O2- site, O2- is bonded in a distorted bent 150 degrees geometry to one U6+ and one I5+ atom. The O–I bond length is 1.84 Å. In the third O2- site, O2- is bonded in a 2-coordinate geometry to one U6+ and one I5+ atom. The O–I bond length is 1.90 Å. In the fourth O2- site, O2- is bonded in a distorted single-bond geometry to two equivalent K1+ and one U6+ atom. In the fifth O2- site, O2- is bonded in a distorted bent 120 degrees geometry to one U6+ and one I5+ atom. The O–I bond length is 1.84 Å.more » In the sixth O2- site, O2- is bonded in a distorted bent 150 degrees geometry to one U6+ and one I5+ atom. The O–I bond length is 1.85 Å. In the seventh O2- site, O2- is bonded in a distorted single-bond geometry to two equivalent K1+ and one I5+ atom. The O–I bond length is 1.82 Å. In the eighth O2- site, O2- is bonded in a distorted trigonal non-coplanar geometry to two equivalent K1+ and one I5+ atom. The O–I bond length is 1.80 Å. In the ninth O2- site, O2- is bonded in a 3-coordinate geometry to one U6+ and two equivalent I5+ atoms. There are one shorter (1.88 Å) and one longer (2.58 Å) O–I bond lengths. In the tenth O2- site, O2- is bonded in a 1-coordinate geometry to two equivalent K1+ and one I5+ atom. The O–I bond length is 1.81 Å. In the eleventh O2- site, O2- is bonded in a distorted single-bond geometry to one I5+ atom. The O–I bond length is 1.82 Å. There are three inequivalent I5+ sites. In the first I5+ site, I5+ is bonded in a 3-coordinate geometry to three O2- atoms. In the second I5+ site, I5+ is bonded in a 5-coordinate geometry to four O2- atoms. In the third I5+ site, I5+ is bonded in a 3-coordinate geometry to three O2- atoms.« less
