Materials Data on U(IO4)2 by Materials Project
U(O4I)2 crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional. U6+ is bonded to eight O2- atoms to form distorted edge-sharing UO8 hexagonal bipyramids. There are a spread of U–O bond distances ranging from 1.82–2.51 Å. There are four inequivalent O2- sites. In the first O2- site, O2- is bonded in a single-bond geometry to one U6+ and one I5+ atom. The O–I bond length is 2.79 Å. In the second O2- site, O2- is bonded in a 1-coordinate geometry to one U6+ and two equivalent I5+ atoms. There are one shorter (1.86 Å) and one longer (2.55 Å) O–I bond lengths. In the third O2- site, O2- is bonded in a 3-coordinate geometry to two equivalent U6+ and one I5+ atom. The O–I bond length is 1.89 Å. In the fourth O2- site, O2- is bonded in a distorted single-bond geometry to two equivalent I5+ atoms. There are one shorter (1.81 Å) and one longer (2.48 Å) O–I bond lengths. I5+ is bonded in a 6-coordinate geometry to six O2- atoms.
