Materials Data on NaAsO2 by Materials Project
NaAsO2 crystallizes in the orthorhombic Pbca space group. The structure is two-dimensional and consists of two NaAsO2 sheets oriented in the (0, 0, 1) direction. Na1+ is bonded in a 4-coordinate geometry to five O2- atoms. There are a spread of Na–O bond distances ranging from 2.32–2.87 Å. As3+ is bonded in a distorted T-shaped geometry to three O2- atoms. There are a spread of As–O bond distances ranging from 1.73–1.88 Å. There are two inequivalent O2- sites. In the first O2- site, O2- is bonded in a 4-coordinate geometry to four equivalent Na1+ and one As3+ atom. In the second O2- site, O2- is bonded in a distorted trigonal planar geometry to one Na1+ and two equivalent As3+ atoms.
