SrTiO3 is (Cubic) Perovskite-like structured and crystallizes in the hexagonal P6_3/mmc space group. There are two inequivalent Sr sites. In the first Sr site, Sr(1) is bonded to three equivalent O(2) and nine equivalent O(1) atoms to form distorted SrO12 cuboctahedra that share corners with three equivalent Sr(2)O12 cuboctahedra, corners with six equivalent Sr(1)O12 cuboctahedra, corners with three equivalent Ti(1)O6 octahedra, faces with three equivalent Sr(2)O12 cuboctahedra, faces with four equivalent Sr(1)O12 cuboctahedra, faces with three equivalent Ti(2)O6 octahedra, and faces with four equivalent Ti(1)O6 octahedra. The corner-sharing octahedral tilt angles are 9°. In the second Sr site, Sr(2) is bonded to six equivalent O(1) and six equivalent O(2) atoms to form SrO12 cuboctahedra that share corners with six equivalent Sr(1)O12 cuboctahedra, corners with six equivalent Sr(2)O12 cuboctahedra, faces with six equivalent Sr(1)O12 cuboctahedra, faces with two equivalent Ti(2)O6 octahedra, and faces with six equivalent Ti(1)O6 octahedra. There are two inequivalent Ti sites. In the first Ti site, Ti(1) is bonded to three equivalent O(1) and three equivalent O(2) atoms to form TiO6 octahedra that share corners with three equivalent Sr(1)O12 cuboctahedra, corners with three equivalent Ti(2)O6 octahedra, faces with three equivalent Sr(2)O12 cuboctahedra, faces with four equivalent Sr(1)O12 cuboctahedra, and  a faceface with one Ti(1)O6 octahedra. The corner-sharing octahedral tilt angles are 4°. In the second Ti site, Ti(2) is bonded to six equivalent O(1) atoms to form TiO6 octahedra that share corners with six equivalent Ti(1)O6 octahedra, faces with two equivalent Sr(2)O12 cuboctahedra, and faces with six equivalent Sr(1)O12 cuboctahedra. The corner-sharing octahedral tilt angles are 4°. There are two inequivalent O sites. In the first O site, O(1) is bonded in a distorted linear geometry to one Sr(2), three equivalent Sr(1), one Ti(1), and one Ti(2) atom. In the second O site, O(2) is bonded to two equivalent Sr(1), two equivalent Sr(2), and two equivalent Ti(1) atoms to form a mixture of distorted face and corner-sharing OSr4Ti2 octahedra. The corner-sharing octahedral tilt angles range from 4-60°.
