The material described by Ti2O3 is Corundum structured and crystallizes in the trigonal R-3c space group. Ti(1) is bonded to six equivalent O(1) atoms to form a mixture of corner, face, and edge-sharing TiO6 octahedra. The corner-sharing octahedral tilt angles range from 47-56°. O(1) is bonded to four equivalent Ti(1) atoms to form a mixture of distorted corner and edge-sharing OTi4 trigonal pyramids. is represented by the Crystallographic Information File (CIF) [CIF]
