Title: Materials Data on RbMg(BrO2)3 by Materials Project

Abstract

RbMg(O2Br)3 crystallizes in the monoclinic C2/c space group. The structure is two-dimensional and consists of two RbMg(O2Br)3 sheets oriented in the (1, 0, 0) direction. Rb1+ is bonded in a 4-coordinate geometry to four O2- atoms. There are two shorter (2.85 Å) and two longer (2.91 Å) Rb–O bond lengths. Mg2+ is bonded in an octahedral geometry to six O2- atoms. There are a spread of Mg–O bond distances ranging from 2.10–2.14 Å. There are three inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted trigonal non-coplanar geometry to one Rb1+, one Mg2+, and one Br3+ atom. The O–Br bond length is 1.78 Å. In the second O2- site, O2- is bonded in a water-like geometry to one Mg2+ and one Br3+ atom. The O–Br bond length is 1.75 Å. In the third O2- site, O2- is bonded in a 3-coordinate geometry to one Rb1+, one Mg2+, and one Br3+ atom. The O–Br bond length is 1.78 Å. There are two inequivalent Br3+ sites. In the first Br3+ site, Br3+ is bonded in a square co-planar geometry to four O2- atoms. In the second Br3+ site, Br3+ is bonded in a single-bond geometry to onemore » O2- atom.« less
