Materials Data on AsO2 by Materials Project
AsO2 crystallizes in the orthorhombic Pnma space group. The structure is two-dimensional and consists of two AsO2 sheets oriented in the (0, 0, 1) direction. there are two inequivalent As sites. In the first As site, As is bonded in a distorted T-shaped geometry to three O atoms. There is two shorter (1.84 Å) and one longer (1.86 Å) As–O bond length. In the second As site, As is bonded in a tetrahedral geometry to four O atoms. There are a spread of As–O bond distances ranging from 1.66–1.76 Å. There are three inequivalent O sites. In the first O site, O is bonded in a single-bond geometry to one As atom. In the second O site, O is bonded in a bent 120 degrees geometry to two As atoms. In the third O site, O is bonded in a bent 120 degrees geometry to two As atoms.
