The crystal structure described by Sm2TeO6 is Hydrophilite-derived structured and crystallizes in the tetragonal P4_2/mnm space group. Sm(1) is bonded to two equivalent O(2) and four equivalent O(1) atoms to form SmO6 octahedra that share corners with four equivalent Sm(1)O6 octahedra, corners with four equivalent Te(1)O6 octahedra,  an edgeedge with one Sm(1)O6 octahedra, and  an edgeedge with one Te(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 43-63°. Te(1) is bonded to two equivalent O(2) and four equivalent O(1) atoms to form TeO6 octahedra that share corners with eight equivalent Sm(1)O6 octahedra and edges with two equivalent Sm(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 43-46°. There are two inequivalent O sites. In the first O site, O(2) is bonded in a distorted T-shaped geometry to two equivalent Sm(1) and one Te(1) atom. In the second O site, O(1) is bonded in a distorted trigonal planar geometry to two equivalent Sm(1) and one Te(1) atom. is represented by the CIF file [CIF]
