GaTiTaO6 is Rutile-derived structured and crystallizes in the tetragonal P4_2nm space group. Ti(1) is bonded to two equivalent O(1), two equivalent O(2), and two equivalent O(3) atoms to form TiO6 octahedra that share corners with four equivalent Ta(1)O6 octahedra, corners with four equivalent Ga(1)O6 octahedra,  an edgeedge with one Ta(1)O6 octahedra, and  an edgeedge with one Ga(1)O6 octahedra. The corner-sharing octahedral tilt angles are 49°. Ta(1) is bonded to two equivalent O(1), two equivalent O(2), and two equivalent O(3) atoms to form TaO6 octahedra that share corners with four equivalent Ti(1)O6 octahedra, corners with four equivalent Ga(1)O6 octahedra,  an edgeedge with one Ti(1)O6 octahedra, and  an edgeedge with one Ga(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 49-50°. Ga(1) is bonded to two equivalent O(1), two equivalent O(2), and two equivalent O(3) atoms to form GaO6 octahedra that share corners with four equivalent Ti(1)O6 octahedra, corners with four equivalent Ta(1)O6 octahedra,  an edgeedge with one Ti(1)O6 octahedra, and  an edgeedge with one Ta(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 49-50°. There are three inequivalent O sites. In the first O site, O(1) is bonded in a distorted trigonal planar geometry to one Ti(1), one Ta(1), and one Ga(1) atom. In the second O site, O(2) is bonded in a distorted trigonal planar geometry to one Ti(1), one Ta(1), and one Ga(1) atom. In the third O site, O(3) is bonded in a distorted trigonal planar geometry to one Ti(1), one Ta(1), and one Ga(1) atom.
