description: Ge11N11O5 is beta indium sulfide-derived structured and crystallizes in the monoclinic Cm space group. The structure is three-dimensional. there are nine inequivalent Ge+3.91+ sites. In the first Ge+3.91+ site, Ge+3.91+ is bonded to five N3- and one O2- atom to form GeN5O octahedra that share corners with five GeN4 tetrahedra and edges with six GeN5O octahedra. There are a spread of Ge–N bond distances ranging from 2.00–2.04 Å. The Ge–O bond length is 1.94 Å. In the second Ge+3.91+ site, Ge+3.91+ is bonded to three N3- and three O2- atoms to form GeN3O3 octahedra that share corners with four GeN4 tetrahedra and edges with six GeN3O3 octahedra. There are a spread of Ge–N bond distances ranging from 1.98–2.03 Å. There are a spread of Ge–O bond distances ranging from 1.92–2.05 Å. In the third Ge+3.91+ site, Ge+3.91+ is bonded to three N3- and one O2- atom to form corner-sharing GeN3O tetrahedra. The corner-sharing octahedra tilt angles range from 56–61°. There is two shorter (1.92 Å) and one longer (1.94 Å) Ge–N bond length. The Ge–O bond length is 2.02 Å. In the fourth Ge+3.91+ site, Ge+3.91+ is bonded to four N3- atoms to form corner-sharing GeN4 tetrahedra. The corner-sharing octahedra tilt angles range from 56–59°. There is one shorter (1.92 Å) and three longer (1.93 Å) Ge–N bond length. In the fifth Ge+3.91+ site, Ge+3.91+ is bonded to five N3- and one O2- atom to form GeN5O octahedra that share corners with six GeN4 tetrahedra and edges with six GeN5O octahedra. There are a spread of Ge–N bond distances ranging from 1.97–2.02 Å. The Ge–O bond length is 2.13 Å. In the sixth Ge+3.91+ site, Ge+3.91+ is bonded to four N3- and two equivalent O2- atoms to form GeN4O2 octahedra that share corners with four GeN4 tetrahedra and edges with six GeN3O3 octahedra. There are a spread of Ge–N bond distances ranging from 2.01–2.05 Å. Both Ge–O bond lengths are 1.95 Å. In the seventh Ge+3.91+ site, Ge+3.91+ is bonded to three N3- and three O2- atoms to form GeN3O3 octahedra that share corners with three equivalent GeN4 tetrahedra and edges with six GeN5O octahedra. All Ge–N bond lengths are 2.00 Å. There is two shorter (1.97 Å) and one longer (1.98 Å) Ge–O bond length. In the eighth Ge+3.91+ site, Ge+3.91+ is bonded to five N3- and one O2- atom to form GeN5O octahedra that share corners with five GeN4 tetrahedra and edges with six GeN5O octahedra. There are three shorter (2.02 Å) and two longer (2.05 Å) Ge–N bond lengths. The Ge–O bond length is 1.96 Å. In the ninth Ge+3.91+ site, Ge+3.91+ is bonded to four N3- atoms to form corner-sharing GeN4 tetrahedra. The corner-sharing octahedra tilt angles range from 55–58°. There is three shorter (1.91 Å) and one longer (1.93 Å) Ge–N bond length. There are eight inequivalent N3- sites. In the first N3- site, N3- is bonded in a distorted rectangular see-saw-like geometry to four Ge+3.91+ atoms. In the second N3- site, N3- is bonded in a distorted rectangular see-saw-like geometry to four Ge+3.91+ atoms. In the third N3- site, N3- is bonded to four Ge+3.91+ atoms to form distorted edge-sharing NGe4 trigonal pyramids. In the fourth N3- site, N3- is bonded to four Ge+3.91+ atoms to form distorted corner-sharing NGe4 trigonal pyramids. In the fifth N3- site, N3- is bonded to four Ge+3.91+ atoms to form a mixture of distorted edge and corner-sharing NGe4 trigonal pyramids. In the sixth N3- site, N3- is bonded in a rectangular see-saw-like geometry to four Ge+3.91+ atoms. In the seventh N3- site, N3- is bonded in a distorted rectangular see-saw-like geometry to four Ge+3.91+ atoms. In the eighth N3- site, N3- is bonded in a distorted rectangular see-saw-like geometry to four Ge+3.91+ atoms. There are four inequivalent O2- sites. In the first O2- site, O2- is bonded in a 3-coordinate geometry to three Ge+3.91+ atoms. In the second O2- site, O2- is bonded in a rectangular see-saw-like geometry to four Ge+3.91+ atoms. In the third O2- site, O2- is bonded in a 3-coordinate geometry to three Ge+3.91+ atoms. In the fourth O2- site, O2- is bonded in a distorted trigonal non-coplanar geometry to three Ge+3.91+ atoms.
