Na2GeTeO6 is Ilmenite-derived structured and crystallizes in the trigonal R3 space group. There are two inequivalent Na sites. In the first Na site, Na(1) is bonded to three equivalent O(1) and three equivalent O(2) atoms to form distorted NaO6 octahedra that share corners with three equivalent Ge(1)O6 octahedra, corners with six equivalent Te(1)O6 octahedra, edges with three equivalent Na(2)O6 octahedra, and  a faceface with one Ge(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 37-58°. In the second Na site, Na(2) is bonded to three equivalent O(1) and three equivalent O(2) atoms to form distorted NaO6 octahedra that share corners with three equivalent Te(1)O6 octahedra, corners with six equivalent Ge(1)O6 octahedra, edges with three equivalent Na(1)O6 octahedra, and  a faceface with one Te(1)O6 octahedra.

The corner-sharing octahedral tilt angles range from 37-59°. There are two inequivalent O sites. In the first O site, O(1) is bonded in a distorted see-saw-like geometry to one Na(1), one Na(2), one Ge(1), and one Te(1) atom. In the second O site, O(2) is bonded in a 4-coordinate geometry to one Na(1), one Na(2), one Ge(1), and one Te(1) atom.
