CaTeO3 crystallizes in the triclinic P-1 space group. The structure is three-dimensional. there are nine inequivalent Ca2+ sites. In the first Ca2+ site, Ca2+ is bonded to six O2- atoms to form CaO6 octahedra that share a cornercorner with one CaO6 octahedra, a cornercorner with one CaO7 pentagonal bipyramid, edges with two equivalent CaO7 hexagonal pyramids, and an edgeedge with one CaO7 pentagonal bipyramid. The corner-sharing octahedral tilt angles are 51°. There are a spread of Ca–O bond distances ranging from 2.32–2.50 Å. In the second Ca2+ site, Ca2+ is bonded to six O2- atoms to form distorted CaO6 octahedra that share a cornercorner with one CaO7 hexagonal pyramid, corners with two CaO6 octahedra, an edgeedge with one CaO6 octahedra, and an edgeedge with one CaO7 pentagonal bipyramid.
