Materials Data on As2O3 by Materials Project
As2O3 crystallizes in the monoclinic P2_1/c space group. The structure is two-dimensional and consists of two As2O3 sheets oriented in the (0, 1, 0) direction. 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 from 1.82–1.84 Å. In the second As3+ site, As3+ is bonded in a trigonal non-coplanar geometry to three O2- atoms. There are a spread of As–O bond distances ranging from 1.81–1.83 Å. There are three inequivalent O2- sites. In the first O2- site, O2- is bonded in a bent 120 degrees geometry to two 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 distorted bent 120 degrees geometry to two As3+ atoms.
