Title: Materials Data on Al11AgO17 by Materials Project

Abstract

AgAl11O17 crystallizes in the orthorhombic Ama2 space group. The structure is three-dimensional. Ag1+ is bonded in a 8-coordinate geometry to eight O2- atoms. There are four shorter (2.77 Å) and four longer (3.09 Å) Ag–O bond lengths. There are five inequivalent Al3+ sites. In the first Al3+ site, Al3+ is bonded to six O2- atoms to form AlO6 octahedra that share corners with five AlO4 tetrahedra and edges with five AlO6 octahedra. There are a spread of Al–O bond distances ranging from 1.82–2.06 Å. In the second Al3+ site, Al3+ is bonded to four O2- atoms to form AlO4 tetrahedra that share corners with six AlO6 octahedra and a cornercorner with one AlO4 tetrahedra. The corner-sharing octahedral tilt angles are 55°. There are a spread of Al–O bond distances ranging from 1.69–1.80 Å. In the third Al3+ site, Al3+ is bonded to four O2- atoms to form corner-sharing AlO4 tetrahedra. The corner-sharing octahedra tilt angles range from 54–58°. There is three shorter (1.82 Å) and one longer (1.83 Å) Al–O bond length. In the fourth Al3+ site, Al3+ is bonded to six O2- atoms to form AlO6 octahedra that share corners with six equivalent AlO4 tetrahedra and edges with sixmore » AlO6 octahedra. There is four shorter (1.91 Å) and two longer (1.92 Å) Al–O bond length. In the fifth Al3+ site, Al3+ is bonded to six O2- atoms to form AlO6 octahedra that share corners with five AlO4 tetrahedra and edges with five AlO6 octahedra. There are a spread of Al–O bond distances ranging from 1.82–2.05 Å. There are eight inequivalent O2- sites. In the first O2- site, O2- is bonded in a rectangular see-saw-like geometry to four Al3+ atoms. The O–Al bond length is 2.06 Å. In the second O2- site, O2- is bonded in a rectangular see-saw-like geometry to four Al3+ atoms. In the third O2- site, O2- is bonded in a distorted trigonal planar geometry to one Ag1+ and three Al3+ atoms. In the fourth O2- site, O2- is bonded in a linear geometry to two equivalent Ag1+ and two equivalent Al3+ atoms. In the fifth O2- site, O2- is bonded in a rectangular see-saw-like geometry to four Al3+ atoms. In the sixth O2- site, O2- is bonded in a 3-coordinate geometry to one Ag1+ and three Al3+ atoms. In the seventh O2- site, O2- is bonded in a trigonal non-coplanar geometry to three Al3+ atoms. In the eighth O2- site, O2- is bonded in a rectangular see-saw-like geometry to four Al3+ atoms.« less
