Sr2NiTeO6 crystallizes in the tetragonal I4/m space group. Sr(1) is bonded to four equivalent O(1) and eight equivalent O(2) atoms to form distorted SrO12 cuboctahedra that share corners with twelve equivalent Sr(1)O12 cuboctahedra, faces with six equivalent Sr(1)O12 cuboctahedra, faces with four equivalent Ni(1)O6 octahedra, and faces with four equivalent Te(1)O6 octahedra. Ni(1) is bonded to two equivalent O(1) and four equivalent O(2) atoms to form NiO6 octahedra that share corners with six equivalent Te(1)O6 octahedra and faces with eight equivalent Sr(1)O12 cuboctahedra. The corner-sharing octahedral tilt angles range from 0-21°. Te(1) is bonded to two equivalent O(1) and four equivalent O(2) atoms to form TeO6 octahedra that share corners with six equivalent Ni(1)O6 octahedra and faces with eight equivalent Sr(1)O12 cuboctahedra. The corner-sharing octahedral tilt angles range from 0-21°. There are two inequivalent O sites. In the first O site, O(1) is bonded to four equivalent Sr(1), one Ni(1), and one Te(1) atom to form a mixture of distorted corner and edge-sharing OSr4NiTe octahedra. The corner-sharing octahedral tilt angles range from 0-3°. In the second O site, O(2) is bonded in a 4-coordinate geometry to four equivalent Sr(1), one Ni(1), and one Te(1) atom.
