Materials Data on IO3 by Materials Project

Abstract

IO3 crystallizes in the orthorhombic P2_12_12_1 space group. The structure is three-dimensional. there are three inequivalent O sites. In the first O site, O is bonded in a 2-coordinate geometry to two equivalent I atoms. There are one shorter (1.85 Å) and one longer (2.40 Å) O–I bond lengths. In the second O site, O is bonded in a distorted bent 150 degrees geometry to two equivalent I atoms. There are one shorter (1.87 Å) and one longer (2.20 Å) O–I bond lengths. In the third O site, O is bonded in a distorted bent 120 degrees geometry to two equivalent I atoms. There are one shorter (1.89 Å) and one longer (2.20 Å) O–I bond lengths. I is bonded to six O atoms to form distorted corner-sharing IO6 octahedra. The corner-sharing octahedra tilt angles range from 45–47°.
