Materials Data on Ag7NO11 by Materials Project
Ag7O8NO3 crystallizes in the trigonal R3m space group. The structure is three-dimensional. there are three inequivalent Ag+2.43+ sites. In the first Ag+2.43+ site, Ag+2.43+ is bonded in a body-centered cubic geometry to eight O2- atoms. There are a spread of Ag–O bond distances ranging from 2.33–2.47 Å. In the second Ag+2.43+ site, Ag+2.43+ is bonded to six O2- atoms to form a mixture of distorted edge and corner-sharing AgO6 octahedra. The corner-sharing octahedral tilt angles are 65°. There are a spread of Ag–O bond distances ranging from 2.11–2.61 Å. In the third Ag+2.43+ site, Ag+2.43+ is bonded in a distorted square co-planar geometry to four O2- atoms. There are two shorter (2.10 Å) and two longer (2.11 Å) Ag–O bond lengths. N5+ is bonded in a trigonal planar geometry to three equivalent O2- atoms. All N–O bond lengths are 1.26 Å. There are five inequivalent O2- sites. In the first O2- site, O2- is bonded to four Ag+2.43+ atoms to form a mixture of edge and corner-sharing OAg4 tetrahedra. 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 edge and corner-sharing OAg4 tetrahedra. In the fourth O2- site, O2- is bonded in a distorted single-bond geometry to two equivalent Ag+2.43+ and one N5+ atom. In the fifth O2- site, O2- is bonded to four Ag+2.43+ atoms to form a mixture of distorted edge and corner-sharing OAg4 tetrahedra.
