Materials Data on Co(IO3)2 by Materials Project

Co(IO3)2 crystallizes in the orthorhombic P2_12_12_1 space group. The structure is three-dimensional. Co2+ is bonded in a 7-coordinate geometry to seven O2- atoms. There are a spread of Co–O bond distances ranging from 2.11–2.71 Å. There are six inequivalent O2- sites. In the first O2- site, O2- is bonded in a 2-coordinate geometry to one Co2+ and three I5+ atoms. There are a spread of O–I bond distances ranging from 1.88–2.75 Å. In the second O2- site, O2- is bonded in a distorted bent 120 degrees geometry to one Co2+ and two I5+ atoms. There are one shorter (1.86 Å) and one longer (2.61 Å) O–I bond lengths. In the third O2- site, O2- is bonded in a 3-coordinate geometry to one Co2+ and two equivalent I5+ atoms. There are one shorter (1.84 Å) and one longer (2.59 Å) O–I bond lengths. In the fourth O2- site, O2- is bonded in a distorted water-like geometry to two equivalent Co2+ and one I5+ atom. The O–I bond length is 1.84 Å. In the fifth O2- site, O2- is bonded in a distorted water-like geometry to one Co2+ and two I5+ atoms. There are one shorter (1.86 Å) and one longer (2.64 Å) O–I bond lengths. In the sixth O2- site, O2- is bonded in a distorted bent 120 degrees geometry to one Co2+ and two equivalent I5+ atoms. There are one shorter (1.88 Å) and one longer (2.53 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 six O2- atoms. In the second I5+ site, I5+ is bonded in a 6-coordinate geometry to six O2- atoms.

Materials Data on Co(IO3)2 by Materials Project

Co(IO3)2 is zeta iron carbide-derived structured and crystallizes in the monoclinic Cm space group. The structure is three-dimensional. Co2+ is bonded to six O2- atoms to form CoO6 octahedra that share corners with twelve equivalent IO6 octahedra. The corner-sharing octahedra tilt angles range from 48–56°. There are a spread of Co–O bond distances ranging from 2.00–2.35 Å. There are four inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted trigonal planar geometry to one Co2+ and two equivalent I5+ atoms. There are one shorter (2.01 Å) and one longer (2.23 Å) O–I bond lengths. In the second O2- site, O2- is bonded in a 3-coordinate geometry to one Co2+ and two equivalent I5+ atoms. Both O–I bond lengths are 2.19 Å. In the third O2- site, O2- is bonded in a distorted trigonal planar geometry to one Co2+ and two equivalent I5+ atoms. There are one shorter (2.07 Å) and one longer (2.13 Å) O–I bond lengths. In the fourth O2- site, O2- is bonded in a 3-coordinate geometry to one Co2+ and two equivalent I5+ atoms. Both O–I bond lengths are 2.25 Å. I5+ is bonded to six O2- atoms to form IO6 octahedra that share corners with six equivalent CoO6 octahedra and edges with three equivalent IO6 octahedra. The corner-sharing octahedra tilt angles range from 48–56°.
