Abstract

Ag2Cu(NO3)4 crystallizes in the triclinic P-1 space group. The structure is three-dimensional. there are two inequivalent Ag1+ sites. In the first Ag1+ site, Ag1+ is bonded in a 8-coordinate geometry to eight O2- atoms. There are a spread of Ag–O bond distances ranging from 2.48–2.97 Å. In the second Ag1+ site, Ag1+ is bonded in a 6-coordinate geometry to seven O2- atoms. There are a spread of Ag–O bond distances ranging from 2.41–2.96 Å. There are two inequivalent Cu2+ sites. In the first Cu2+ site, Cu2+ is bonded in a square co-planar geometry to four O2- atoms. There are two shorter (1.99 Å) and two longer (2.02 Å) Cu–O bond lengths. In the second Cu2+ site, Cu2+ is bonded in a square co-planar geometry to four O2- atoms. All Cu–O bond lengths are 2.01 Å. There are four inequivalent N5+ sites. In the first N5+ site, N5+ is bonded in a trigonal planar geometry to three O2- atoms. There are a spread of N–O bond distances ranging from 1.25–1.30 Å. In the second N5+ site, N5+ is bonded in a trigonal planar geometry to three O2- atoms. There are a spread of N–O bond distances ranging from 1.24–1.32 Å. In the third N5+ site, N5+ is bonded in a trigonal planar geometry to three O2- atoms. There are a spread of N–O bond distances ranging from 1.24–1.31 Å. In the fourth N5+ site, N5+ is bonded in a trigonal planar geometry to three O2- atoms. There is two shorter (1.25 Å) and one longer (1.32 Å) N–O bond length. There are twelve inequivalent O2- sites. In the first O2- site, O2- is bonded in a 2-coordinate geometry to one Ag1+, one Cu2+, and one N5+ atom. In the second O2- site, O2- is bonded in a distorted single-bond geometry to one Ag1+ and one N5+ atom. In the third O2- site, O2- is bonded in a distorted single-bond geometry to two Ag1+ and one N5+ atom. In the fourth O2- site, O2- is bonded in a distorted water-like geometry to one Ag1+, one Cu2+, and one N5+ atom. In the fifth O2- site, O2- is bonded in a 1-coordinate geometry to two equivalent Ag1+ and one N5+ atom. In the sixth O2- site, O2- is bonded in a distorted water-like geometry to one Ag1+ and one N5+ atom. In the seventh O2- site, O2- is bonded in a 3-coordinate geometry to one Ag1+, one Cu2+, and one N5+ atom. In the eighth O2- site, O2- is bonded in a distorted single-bond geometry to two Ag1+ and one N5+ atom. In the ninth O2- site, O2- is bonded in a distorted single-bond geometry to one Ag1+ and one N5+ atom. In the tenth O2- site, O2- is bonded in a 3-coordinate geometry to one Ag1+, one Cu2+, and one N5+ atom. In the eleventh O2- site, O2- is bonded in a 2-coordinate geometry to one Ag1+ and one N5+ atom. In the twelfth O2- site, O2- is bonded in a distorted single-bond geometry to one Ag1+ and one N5+ atom.
