Materials Data on CuHIO4 by Materials Project

Cu(OH)IO3 crystallizes in the orthorhombic Pnma space group. The structure is three-dimensional. Cu2+ is bonded to six O2- atoms to form distorted edge-sharing CuO6 octahedra. There are four shorter (1.99 Å) and two longer (2.57 Å) Cu–O bond lengths. H1+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 1.00 Å. There are three inequivalent O2- sites. In the first O2- site, O2- is bonded in a 1-coordinate geometry to two equivalent Cu2+ and one I5+ atom. The O–I bond length is 1.83 Å. In the second O2- site, O2- is bonded in a distorted water-like geometry to one Cu2+ and two equivalent I5+ atoms. There are one shorter (1.89 Å) and one longer (2.73 Å) O–I bond lengths. In the third O2- site, O2- is bonded in a 1-coordinate geometry to two equivalent Cu2+, one H1+, and one I5+ atom. The O–I bond length is 2.46 Å. I5+ is bonded in a 6-coordinate geometry to six O2- atoms.
