The compound described by Ti4O3 crystallizes in the tetragonal I4/mmm space group. There are two inequivalent Ti sites. In the first Ti site, Ti(1) is bonded in a square co-planar geometry to two equivalent O(1) and two equivalent O(2) atoms. In the second Ti site, Ti(2) is bonded to one O(2) and four equivalent O(1) atoms to form a mixture of corner and edge-sharing TiO5 square pyramids. There are two inequivalent O sites. In the first O site, O(1) is bonded to two equivalent Ti(1) and four equivalent Ti(2) atoms to form a mixture of corner and edge-sharing OTi6 octahedra. The corner-sharing octahedral tilt angles range from 0-10°. In the second O site, O(2) is bonded to two equivalent Ti(2) and four equivalent Ti(1) atoms to form a mixture of corner and edge-sharing OTi6 octahedra. The corner-sharing octahedra are not tilted. is represented by the CIF card [CIF]
