Abstract

Ag7O8NO3 crystallizes in the orthorhombic Fmm2 space group. The structure is three-dimensional. there are four inequivalent Ag+2.43+ sites. In the first Ag+2.43+ site, Ag+2.43+ is bonded in a 4-coordinate geometry to five O2- atoms. There are four shorter (2.10 Å) and one longer (2.74 Å) Ag–O bond lengths. In the second Ag+2.43+ site, Ag+2.43+ is bonded in a 6-coordinate geometry to six O2- atoms. There are a spread of Ag–O bond distances ranging from 2.13–2.74 Å. In the third Ag+2.43+ site, Ag+2.43+ is bonded in a distorted square co-planar geometry to four O2- atoms. All Ag–O bond lengths are 2.10 Å. In the fourth Ag+2.43+ site, Ag+2.43+ is bonded in a body-centered cubic geometry to eight O2- atoms. All Ag–O bond lengths are 2.42 Å. N5+ is bonded in a trigonal planar geometry to three O2- atoms. There is two shorter (1.26 Å) and one longer (1.27 Å) N–O bond length. There are four inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted single-bond geometry to one Ag+2.43+ and one N5+ atom. In the second O2- site, O2- is bonded to four Ag+2.43+ atoms to form a mixture of distorted edge and corner-sharing OAg4 tetrahedra. In the third O2- site, O2- is bonded to four Ag+2.43+ atoms to form a mixture of distorted edge and corner-sharing OAg4 tetrahedra. In the fourth O2- site, O2- is bonded in a distorted single-bond geometry to four Ag+2.43+ and one N5+ atom.
