Materials Data on Mg(BrO3)2 by Materials Project

Abstract

Mg(O3Br)2 crystallizes in the monoclinic C2/m space group. The structure is one-dimensional and consists of two Mg(O3Br)2 ribbons oriented in the (0, 0, 1) direction. Mg2+ is bonded in an octahedral geometry to six O2- atoms. There are two shorter (1.99 Å) and four longer (2.18 Å) Mg–O bond lengths. There are two inequivalent O2- sites. In the first O2- site, O2- is bonded in a 1-coordinate geometry to one Mg2+ and one O2- atom. The O–O bond length is 1.29 Å. In the second O2- site, O2- is bonded in a distorted bent 150 degrees geometry to one Mg2+ and one Br5+ atom. The O–Br bond length is 1.76 Å. Br5+ is bonded in a single-bond geometry to one O2- atom.
