Co2TiO4 is Spinel-like structured and crystallizes in the orthorhombic Imma space group. Ti(1) is bonded to two equivalent O(2) and four equivalent O(1) atoms to form TiO6 octahedra that share corners with six equivalent Co(1)O4 tetrahedra, edges with two equivalent Ti(1)O6 octahedra, and edges with four equivalent Co(2)O6 octahedra. There are two inequivalent Co sites. In the first Co site, Co(1) is bonded to two equivalent O(1) and two equivalent O(2) atoms to form CoO4 tetrahedra that share corners with six equivalent Ti(1)O6 octahedra and corners with six equivalent Co(2)O6 octahedra. The corner-sharing octahedral tilt angles range from 56-59°. In the second Co site, Co(2) is bonded to two equivalent O(1) and four equivalent O(2) atoms to form CoO6 octahedra that share corners with six equivalent Co(1)O4 tetrahedra, edges with two equivalent Co(2)O6 octahedra, and edges with four equivalent Ti(1)O6 octahedra. There are two inequivalent O sites. In the first O site, O(1) is bonded in a rectangular see-saw-like geometry to two equivalent Ti(1), one Co(1), and one Co(2) atom. In the second O site, O(2) is bonded to one Ti(1), one Co(1), and two equivalent Co(2) atoms to form a mixture of distorted corner and edge-sharing OTiCo3 trigonal pyramids.
