CaTiO3 is Ilmenite structured and crystallizes in the trigonal R-3 space group. Ca(1) is bonded to six equivalent O(1) atoms to form distorted CaO6 pentagonal pyramids that share corners with nine equivalent Ti(1)O6 octahedra, edges with three equivalent Ca(1)O6 pentagonal pyramids, and  a faceface with one Ti(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 38-64°. Ti(1) is bonded to six equivalent O(1) atoms to form distorted TiO6 octahedra that share corners with nine equivalent Ca(1)O6 pentagonal pyramids, edges with three equivalent Ti(1)O6 octahedra, and  a faceface with one Ca(1)O6 pentagonal pyramid. O(1) is bonded in a distorted see-saw-like geometry to two equivalent Ca(1) and two equivalent Ti(1) atoms.

The corner-sharing octahedral tilt angles range from 38-64°. There are three shorter (2.30 Å) and three longer (2.44 Å) Ca(1)-O(1) bond lengths. Ti(1) is bonded to six equivalent O(1) atoms to form distorted TiO6 octahedra that share corners with nine equivalent Ca(1)O6 pentagonal pyramids, edges with three equivalent Ti(1)O6 octahedra, and  a faceface with one Ca(1)O6 pentagonal pyramid. There are three shorter (1.90 Å) and three longer (2.13 Å) Ti(1)-O(1) bond lengths. O(1) is bonded in a distorted see-saw-like geometry to two equivalent Ca(1) and two equivalent Ti(1) atoms.
