RbNbTeO6 crystallizes in the orthorhombic Imma space group. Rb(1) is bonded to one O(1), one O(2), and four equivalent O(3) atoms to form RbO6 octahedra that share corners with six equivalent Nb(1)O6 octahedra and corners with six equivalent Te(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 67-71°. Nb(1) is bonded to two equivalent O(2) and four equivalent O(3) atoms to form NbO6 octahedra that share corners with two equivalent Nb(1)O6 octahedra, corners with four equivalent Te(1)O6 octahedra, and corners with six equivalent Rb(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 39-71°. Te(1) is bonded to two equivalent O(1) and four equivalent O(3) atoms to form TeO6 octahedra that share corners with two equivalent Te(1)O6 octahedra, corners with four equivalent Nb(1)O6 octahedra, and corners with six equivalent Rb(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 41-68°. There are three inequivalent O sites. In the first O site, O(1) is bonded in a 2-coordinate geometry to one Rb(1) and two equivalent Te(1) atoms. In the second O site, O(2) is bonded in a distorted bent 150 degrees geometry to one Rb(1) and two equivalent Nb(1) atoms. In the third O site, O(3) is bonded in a distorted bent 150 degrees geometry to one Rb(1), one Nb(1), and one Te(1) atom.
