Abstract

Cd(IO3)2 crystallizes in the orthorhombic Pca2_1 space group. The structure is three-dimensional. there are two inequivalent Cd2+ sites. In the first Cd2+ site, Cd2+ is bonded in a 6-coordinate geometry to six O2- atoms. There are a spread of Cd–O bond distances ranging from 2.28–2.42 Å. In the second Cd2+ site, Cd2+ is bonded in a 7-coordinate geometry to seven O2- atoms. There are a spread of Cd–O bond distances ranging from 2.28–2.68 Å. There are twelve inequivalent O2- sites. In the first 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 (2.73 Å) O–I bond lengths. In the second O2- site, O2- is bonded in a distorted bent 150 degrees geometry to one Cd2+ and one I5+ atom. The O–I bond length is 1.84 Å. In the third O2- site, O2- is bonded in a distorted single-bond geometry to one I5+ atom. The O–I bond length is 1.83 Å. In the fourth O2- site, O2- is bonded in a distorted trigonal planar geometry to two Cd2+ and one I5+ atom. The O–I bond length is 1.85 Å. In the fifth O2- site, O2- is bonded in a distorted single-bond geometry to one I5+ atom. The O–I bond length is 1.84 Å. In the sixth 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 seventh O2- site, O2- is bonded in a distorted trigonal planar geometry to two Cd2+ and one I5+ atom. The O–I bond length is 1.86 Å. In the eighth O2- site, O2- is bonded in a 2-coordinate geometry to one Cd2+ and two I5+ atoms. There are one shorter (1.84 Å) and one longer (2.69 Å) O–I bond lengths. In the ninth O2- site, O2- is bonded in a 2-coordinate geometry to one Cd2+ and one I5+ atom. The O–I bond length is 1.86 Å. In the tenth O2- site, O2- is bonded in a distorted single-bond geometry to one Cd2+ and one I5+ atom. The O–I bond length is 1.87 Å. In the eleventh O2- site, O2- is bonded in a distorted trigonal planar geometry to two Cd2+ and one I5+ atom. The O–I bond length is 1.89 Å. In the twelfth O2- site, O2- is bonded in a 2-coordinate geometry to one Cd2+ and two I5+ atoms. There are one shorter (1.83 Å) and one longer (2.72 Å) O–I bond lengths. There are four 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 3-coordinate geometry to four O2- atoms. In the third I5+ site, I5+ is bonded in a 6-coordinate geometry to three O2- atoms. In the fourth I5+ site, I5+ is bonded in a 3-coordinate geometry to four O2- atoms.
