description: Na4Al3Ge3NO14 crystallizes in the monoclinic Cc space group. The structure is three-dimensional. there are four inequivalent Na1+ sites. In the first Na1+ site, Na1+ is bonded to four O2- atoms to form NaO4 tetrahedra that share a cornercorner with one NaO4 tetrahedra, corners with three AlO4 tetrahedra, and corners with three GeO4 tetrahedra. There are a spread of Na–O bond distances ranging from 2.34–2.44 Å. In the second Na1+ site, Na1+ is bonded to four O2- atoms to form NaO4 tetrahedra that share a cornercorner with one NaO4 tetrahedra, corners with three AlO4 tetrahedra, and corners with three GeO4 tetrahedra. There are a spread of Na–O bond distances ranging from 2.34–2.44 Å. In the third Na1+ site, Na1+ is bonded to four O2- atoms to form distorted NaO4 tetrahedra that share a cornercorner with one NaO4 tetrahedra, corners with three AlO4 tetrahedra, and corners with three GeO4 tetrahedra.

There are three inequivalent Ge4+ sites. In the first Ge4+ site, Ge4+ is bonded to four O2- atoms to form GeO4 tetrahedra that share corners with four NaO4 tetrahedra and corners with four AlO4 tetrahedra. There is three shorter (1.76 Å) and one longer (1.77 Å) Ge–O bond length. In the second Ge4+ site, Ge4+ is bonded to four O2- atoms to form GeO4 tetrahedra that share corners with four NaO4 tetrahedra and corners with four AlO4 tetrahedra. There is two shorter (1.76 Å) and two longer (1.77 Å) Ge–O bond length. In the third Ge4+ site, Ge4+ is bonded to four O2- atoms to form GeO4 tetrahedra that share corners with four NaO4 tetrahedra and corners with four AlO4 tetrahedra. There is three shorter (1.76 Å) and one longer (1.77 Å) Ge–O bond length. N3+ is bonded in a bent 120 degrees geometry to two O2- atoms. There is one shorter (1.27 Å) and one longer (1.28 Å) N–O bond length. There are fourteen inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted trigonal planar geometry to one Na1+, one Al3+, and one Ge4+ atom. In the second O2- site, O2- is bonded in a distorted trigonal planar geometry to one Na1+, one Al3+, and one Ge4+ atom.
