BaDyTb2O6 crystallizes in the monoclinic P2_1/m space group. Ba(1) is bonded in a 8-coordinate geometry to one O(1), one O(2), two equivalent O(4), and four equivalent O(3) atoms. Dy(1) is bonded in a 6-coordinate geometry to one O(1), one O(2), two equivalent O(3), and two equivalent O(4) atoms. There are two inequivalent Tb sites. In the first Tb site, Tb(1) is bonded to two equivalent O(2), two equivalent O(3), and two equivalent O(4) atoms to form corner-sharing TbO6 octahedra. The corner-sharing octahedral tilt angles range from 32-49°. In the second Tb site, Tb(2) is bonded to two equivalent O(1), two equivalent O(3), and two equivalent O(4) atoms to form corner-sharing TbO6 octahedra. The corner-sharing octahedral tilt angles range from 32-45°. There are four inequivalent O sites. In the first O site, O(1) is bonded to one Ba(1), one Dy(1), and two equivalent Tb(2) atoms to form distorted corner-sharing OBaTb2Dy trigonal pyramids. In the second O site, O(2) is bonded to one Ba(1), one Dy(1), and two equivalent Tb(1) atoms to form distorted corner-sharing OBaTb2Dy trigonal pyramids. In the third O site, O(3) is bonded in a 5-coordinate geometry to two equivalent Ba(1), one Dy(1), one Tb(1), and one Tb(2) atom. In the fourth O site, O(4) is bonded in a 4-coordinate geometry to one Ba(1), one Dy(1), one Tb(1), and one Tb(2) atom.
