Title: Materials Data on UI4O15 by Materials Project

Abstract

UO15I4 crystallizes in the orthorhombic Pbcn space group. The structure is two-dimensional and consists of two UO15I4 sheets oriented in the (0, 0, 1) direction. U is bonded in a distorted pentagonal bipyramidal geometry to seven O atoms. There are a spread of U–O bond distances ranging from 1.83–2.41 Å. There are eight inequivalent O sites. In the first O site, O is bonded in a distorted single-bond geometry to one I atom. The O–I bond length is 1.85 Å. In the second O site, O is bonded in a distorted bent 120 degrees geometry to two I atoms. There are one shorter (1.85 Å) and one longer (2.45 Å) O–I bond lengths. In the third O site, O is bonded in a bent 150 degrees geometry to one U and one I atom. The O–I bond length is 1.83 Å. In the fourth O site, O is bonded in a single-bond geometry to one I atom. The O–I bond length is 1.85 Å. In the fifth O site, O is bonded in a single-bond geometry to one U atom. In the sixth O site, O is bonded in a single-bond geometry to one U atom. In the seventh Omore » site, O is bonded in a single-bond geometry to one I atom. The O–I bond length is 1.86 Å. In the eighth O site, O is bonded in a bent 150 degrees geometry to one U and one I atom. The O–I bond length is 1.88 Å. There are two inequivalent I sites. In the first I site, I is bonded in a 3-coordinate geometry to three O atoms. In the second I site, I is bonded in a 5-coordinate geometry to four O atoms.« less
