The crystal structure described by TiTaSbO6 crystallizes in the triclinic P-1 space group. Ti(1) is bonded to one O(1), one O(2), one O(3), one O(5), and two equivalent O(4) atoms to form distorted TiO6 octahedra that share corners with six equivalent Ta(1)O6 octahedra and  an edgeedge with one Ti(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 38-53°. Ta(1) is bonded to one O(1), one O(2), one O(4), one O(6), and two equivalent O(3) atoms to form distorted TaO6 octahedra that share corners with six equivalent Ti(1)O6 octahedra and  an edgeedge with one Ta(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 38-53°. Sb(1) is bonded in a rectangular see-saw-like geometry to two equivalent O(5) and two equivalent O(6) atoms. There are six inequivalent O sites. In the first O site, O(1) is bonded in a bent 150 degrees geometry to one Ti(1) and one Ta(1) atom. In the second O site, O(2) is bonded in a bent 150 degrees geometry to one Ti(1) and one Ta(1) atom. In the third O site, O(3) is bonded in a distorted trigonal planar geometry to one Ti(1) and two equivalent Ta(1) atoms. In the fourth O site, O(4) is bonded in a distorted trigonal planar geometry to two equivalent Ti(1) and one Ta(1) atom. In the fifth O site, O(5) is bonded in a distorted trigonal planar geometry to one Ti(1) and two equivalent Sb(1) atoms. In the sixth O site, O(6) is bonded in a distorted trigonal planar geometry to one Ta(1) and two equivalent Sb(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
