Na3Te(PO7)2 crystallizes in the hexagonal P6_322 space group. Na(1) is bonded to two equivalent O(1), two equivalent O(2), and two equivalent O(3) atoms to form distorted NaO6 octahedra that share corners with two equivalent Te(1)O6 octahedra, corners with four equivalent P(1)O4 tetrahedra, and edges with two equivalent Na(1)O6 octahedra. The corner-sharing octahedral tilt angles are 47°. P(1) is bonded to one O(2) and three equivalent O(3) atoms to form PO4 tetrahedra that share corners with six equivalent Na(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 44-54°. Te(1) is bonded to six equivalent O(1) atoms to form distorted TeO6 octahedra that share corners with six equivalent Na(1)O6 octahedra. The corner-sharing octahedral tilt angles are 47°. There are three inequivalent O sites. In the first O site, O(1) is bonded in a distorted bent 120 degrees geometry to one Na(1) and one Te(1) atom. In the second O site, O(2) is bonded in a rectangular see-saw-like geometry to three equivalent Na(1) and one P(1) atom. In the third O site, O(3) is bonded in a distorted bent 150 degrees geometry to one Na(1) and one P(1) atom.
