Materials Data on Cd(IO3)2 by Materials Project
Cd(IO3)2 crystallizes in the orthorhombic P2_12_12_1 space group. The structure is three-dimensional. Cd2+ is bonded to seven O2- atoms to form distorted corner-sharing CdO7 pentagonal bipyramids. There are a spread of Cd–O bond distances ranging from 2.31–2.53 Å. There are six inequivalent O2- sites. In the first O2- site, O2- is bonded in a 2-coordinate geometry to one Cd2+ and two equivalent I5+ atoms. There are one shorter (1.84 Å) and one longer (2.73 Å) O–I bond lengths. In the second O2- site, O2- is bonded in a 3-coordinate geometry to two equivalent Cd2+ and one I5+ atom. The O–I bond length is 1.85 Å. In the third O2- site, O2- is bonded in a 1-coordinate geometry to one Cd2+ and one I5+ atom. The O–I bond length is 1.86 Å. In the fourth O2- site, O2- is bonded in a 2-coordinate geometry to one Cd2+ and two equivalent I5+ atoms. There are one shorter (1.86 Å) and one longer (2.62 Å) O–I bond lengths. In the fifth O2- site, O2- is bonded in a 2-coordinate geometry to one Cd2+ and one I5+ atom. The O–I bond length is 1.85 Å. In the sixth O2- site, O2- is bonded in a 2-coordinate geometry to one Cd2+ and two I5+ atoms. There are one shorter (1.86 Å) and one longer (2.58 Å) O–I bond lengths. There are two inequivalent I5+ sites. In the first I5+ site, I5+ is bonded in a 6-coordinate geometry to four O2- atoms. In the second I5+ site, I5+ is bonded in a 6-coordinate geometry to five O2- atoms.
