Title: Materials Data on RbAsO2 by Materials Project

Abstract

RbAsO2 crystallizes in the orthorhombic Pbcm space group. The structure is two-dimensional and consists of one RbAsO2 sheet oriented in the (0, 1, 0) direction. Rb1+ is bonded in a 8-coordinate geometry to eight O2- atoms. There are a spread of Rb–O bond distances ranging from 2.90–3.40 Å. As3+ is bonded in a distorted T-shaped geometry to three O2- atoms. There is one shorter (1.72 Å) and two longer (1.89 Å) As–O bond length. There are two inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted bent 120 degrees geometry to four equivalent Rb1+ and two equivalent As3+ atoms. In the second O2- site, O2- is bonded in a 1-coordinate geometry to four equivalent Rb1+ and one As3+ atom.
