Title: Materials Data on As2O3 by Materials Project

Abstract

As2O3 crystallizes in the monoclinic P2_1 space group. The structure is two-dimensional and consists of two As2O3 sheets oriented in the (0, 0, 1) direction. In one of the As2O3 sheets, there are two inequivalent As3+ sites. In the first As3+ site, As3+ is bonded in a distorted T-shaped geometry to three O2- atoms. There is two shorter (1.82 Å) and one longer (1.84 Å) As–O bond length. In the second As3+ site, As3+ is bonded in a distorted trigonal non-coplanar geometry to three O2- atoms. There are a spread of As–O bond distances ranging from 1.82–1.84 Å. There are three inequivalent O2- sites. In the first O2- site, O2- is bonded in a bent 120 degrees geometry to two equivalent As3+ atoms. In the second O2- site, O2- is bonded in a distorted bent 150 degrees geometry to two As3+ atoms. In the third O2- site, O2- is bonded in a bent 120 degrees geometry to two equivalent As3+ atoms. In one of the As2O3 sheets, there are two inequivalent As3+ sites. In the first As3+ site, As3+ is bonded in a distorted T-shaped geometry to three O2- atoms. There are a spread of As–O bond distances ranging frommore » 1.81–1.85 Å. In the second As3+ site, As3+ is bonded in a distorted T-shaped geometry to three O2- atoms. There are a spread of As–O bond distances ranging from 1.81–1.85 Å. There are three inequivalent O2- sites. In the first O2- site, O2- is bonded in a bent 120 degrees geometry to two equivalent As3+ atoms. In the second O2- site, O2- is bonded in a bent 120 degrees geometry to two As3+ atoms. In the third O2- site, O2- is bonded in a bent 120 degrees geometry to two equivalent As3+ atoms.« less
