Materials Data on Ag7NO8 by Materials Project
Ag7NO8 crystallizes in the cubic Fm-3m space group. The structure is three-dimensional. there are two inequivalent Ag+1.57+ sites. In the first Ag+1.57+ site, Ag+1.57+ is bonded in a body-centered cubic geometry to eight equivalent O2- atoms. All Ag–O bond lengths are 2.27 Å. In the second Ag+1.57+ site, Ag+1.57+ is bonded in a 5-coordinate geometry to one N5+ and four equivalent O2- atoms. The Ag–N bond length is 2.19 Å. All Ag–O bond lengths are 2.39 Å. N5+ is bonded to six equivalent Ag+1.57+ atoms to form NAg6 octahedra that share corners with twenty-four equivalent OAg4 tetrahedra. O2- is bonded to four Ag+1.57+ atoms to form distorted OAg4 tetrahedra that share corners with three equivalent NAg6 octahedra, a cornercorner with one OAg4 tetrahedra, edges with three equivalent OAg4 tetrahedra, and faces with three equivalent OAg4 tetrahedra. The corner-sharing octahedral tilt angles are 51°.
