Materials Data on IO2F by Materials Project
O2IF crystallizes in the orthorhombic P2_12_12_1 space group. The structure is one-dimensional and consists of two O2IF ribbons oriented in the (0, 1, 0) direction. there are two inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted bent 150 degrees geometry to two equivalent I5+ atoms. There are one shorter (1.84 Å) and one longer (2.23 Å) O–I bond lengths. In the second O2- site, O2- is bonded in a distorted single-bond geometry to one I5+ atom. The O–I bond length is 1.79 Å. I5+ is bonded in a 4-coordinate geometry to three O2- and one F1- atom. The I–F bond length is 1.95 Å. F1- is bonded in a single-bond geometry to one I5+ atom.
