The compound described by Ga2TiO5 crystallizes in the orthorhombic Cmcm space group. Ti(1) is bonded to two equivalent O(1), two equivalent O(2), and two equivalent O(3) atoms to form distorted TiO6 octahedra that share corners with two equivalent Ti(1)O6 octahedra, corners with two equivalent Ga(1)O6 octahedra, and edges with six equivalent Ga(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 27-43°. Ga(1) is bonded to one O(3), two equivalent O(1), and three equivalent O(2) atoms to form distorted GaO6 octahedra that share  a cornercorner with one Ti(1)O6 octahedra, corners with three equivalent Ga(1)O6 octahedra, edges with three equivalent Ti(1)O6 octahedra, and edges with three equivalent Ga(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 27-60°. There are three inequivalent O sites. In the first O site, O(1) is bonded in a distorted T-shaped geometry to one Ti(1) and two equivalent Ga(1) atoms. In the second O site, O(2) is bonded to one Ti(1) and three equivalent Ga(1) atoms to form distorted OTiGa3 trigonal pyramids that share  a cornercorner with one O(3)Ti2Ga2 tetrahedra, corners with three equivalent O(2)TiGa3 trigonal pyramids, edges with two equivalent O(3)Ti2Ga2 tetrahedra, and edges with two equivalent O(2)TiGa3 trigonal pyramids. In the third O site, O(3) is bonded to two equivalent Ti(1) and two equivalent Ga(1) atoms to form distorted OTi2Ga2 tetrahedra that share corners with two equivalent O(3)Ti2Ga2 tetrahedra, corners with two equivalent O(2)TiGa3 trigonal pyramids, and edges with four equivalent O(2)TiGa3 trigonal pyramids. is represented by the Crystallographic Information File (CIF) [CIF]
