Materials Data on NaAg(NO2)2 by Materials Project

Abstract

NaAg(NO2)2 crystallizes in the orthorhombic Fdd2 space group. The structure is three-dimensional. Na1+ is bonded to six O2- atoms to form distorted corner-sharing NaO6 pentagonal pyramids. There are a spread of Na–O bond distances ranging from 2.48–2.60 Å. Ag1+ is bonded in a 7-coordinate geometry to one N3+ and six O2- atoms. The Ag–N bond length is 2.19 Å. There are a spread of Ag–O bond distances ranging from 2.42–3.02 Å. There are two inequivalent N3+ sites. In the first N3+ site, N3+ is bonded in a bent 120 degrees geometry to two equivalent O2- atoms. Both N–O bond lengths are 1.27 Å. In the second N3+ site, N3+ is bonded in a trigonal planar geometry to one Ag1+ and two equivalent O2- atoms. Both N–O bond lengths are 1.26 Å. There are two inequivalent O2- sites. In the first O2- site, O2- is bonded in a 4-coordinate geometry to two equivalent Na1+, one Ag1+, and one N3+ atom. In the second O2- site, O2- is bonded in a 1-coordinate geometry to one Na1+, two equivalent Ag1+, and one N3+ atom.
