The compound described by YbTiTaO6 crystallizes in the monoclinic P2_1/c space group. Yb(1) is bonded in a 8-coordinate geometry to two equivalent O(1), two equivalent O(2), two equivalent O(3), and two equivalent O(4) atoms. Ti(1) is bonded in a 6-coordinate geometry to one O(1), one O(2), one O(3), one O(6), and two equivalent O(5) atoms. Ta(1) is bonded to one O(1), one O(2), one O(4), one O(5), and two equivalent O(6) atoms to form distorted corner-sharing TaO6 octahedra. The corner-sharing octahedral tilt angles are 53°. There are six inequivalent O sites. In the first O site, O(1) is bonded in a 4-coordinate geometry to two equivalent Yb(1), one Ti(1), and one Ta(1) atom. In the second O site, O(2) is bonded in a 4-coordinate geometry to two equivalent Yb(1), one Ti(1), and one Ta(1) atom. In the third O site, O(3) is bonded in a 3-coordinate geometry to two equivalent Yb(1) and one Ti(1) atom. In the fourth O site, O(4) is bonded in a distorted trigonal non-coplanar geometry to two equivalent Yb(1) and one Ta(1) atom. In the fifth O site, O(5) is bonded in a 3-coordinate geometry to two equivalent Ti(1) and one Ta(1) atom. In the sixth O site, O(6) is bonded in a distorted trigonal planar geometry to one Ti(1) and two equivalent Ta(1) atoms. is represented by the CIF card [CIF]
