Materials Data on Mn(IO2)2 by Materials Project

Abstract

Mn(O2I)2 crystallizes in the monoclinic P2_1/c space group. The structure is one-dimensional and consists of two Mn(O2I)2 ribbons oriented in the (1, 0, 1) direction. Mn4+ is bonded in a square co-planar geometry to four O2- atoms. There is two shorter (1.88 Å) and two longer (1.89 Å) Mn–O bond length. There are two inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted bent 150 degrees geometry to one Mn4+ and one I2+ atom. The O–I bond length is 2.00 Å. In the second O2- site, O2- is bonded in a distorted bent 150 degrees geometry to one Mn4+ and one I2+ atom. The O–I bond length is 2.03 Å. I2+ is bonded in a linear geometry to two O2- atoms.
