Materials Data on NaAg(NO2)2 by Materials Project
NaAg(NO2)2 crystallizes in the orthorhombic F222 space group. The structure is three-dimensional. there are two inequivalent Na1+ sites. In the first Na1+ site, Na1+ is bonded in a square co-planar geometry to four equivalent O2- atoms. All Na–O bond lengths are 2.45 Å. In the second Na1+ site, Na1+ is bonded in a 8-coordinate geometry to eight O2- atoms. There are four shorter (2.54 Å) and four longer (2.76 Å) Na–O bond lengths. There are two inequivalent Ag1+ sites. In the first Ag1+ site, Ag1+ is bonded in a distorted body-centered cubic geometry to eight O2- atoms. There are four shorter (2.45 Å) and four longer (3.06 Å) Ag–O bond lengths. In the second Ag1+ site, Ag1+ is bonded in a distorted linear geometry to two equivalent N3+ and four equivalent O2- atoms. Both Ag–N bond lengths are 2.17 Å. All Ag–O bond lengths are 2.99 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 2-coordinate geometry to two Na1+, one Ag1+, and one N3+ atom. In the second O2- site, O2- is bonded in a 4-coordinate geometry to one Na1+, two Ag1+, and one N3+ atom.
