Materials Data on CdIO4 by Materials Project
CdO4I crystallizes in the orthorhombic Pnma space group. The structure is three-dimensional. Cd is bonded to six O atoms to form edge-sharing CdO6 octahedra. There are a spread of Cd–O bond distances ranging from 2.28–2.38 Å. There are three inequivalent O sites. In the first O site, O is bonded in a distorted bent 120 degrees geometry to one Cd and one I atom. The O–I bond length is 1.84 Å. In the second O site, O is bonded in a distorted trigonal planar geometry to two equivalent Cd and one I atom. The O–I bond length is 1.94 Å. In the third O site, O is bonded in a trigonal non-coplanar geometry to two equivalent Cd and one I atom. The O–I bond length is 1.99 Å. I is bonded in a distorted see-saw-like geometry to four O atoms.
