BaDyTb4O12 crystallizes in the orthorhombic Amm2 space group. Ba(1) is bonded in a 10-coordinate geometry to two equivalent O(2), four equivalent O(1), and four equivalent O(4) atoms. Dy(1) is bonded in a 6-coordinate geometry to two equivalent O(2), two equivalent O(3), and two equivalent O(5) atoms. Tb(1) is bonded to one O(2), one O(3), one O(4), one O(5), and two equivalent O(1) atoms to form distorted corner-sharing TbO6 pentagonal pyramids. There are five inequivalent O sites. In the first O site, O(1) is bonded in a distorted trigonal planar geometry to one Ba(1) and two equivalent Tb(1) atoms. In the second O site, O(2) is bonded in a square co-planar geometry to one Ba(1), one Dy(1), and two equivalent Tb(1) atoms. In the third O site, O(3) is bonded in a trigonal planar geometry to one Dy(1) and two equivalent Tb(1) atoms. In the fourth O site, O(4) is bonded in a 2-coordinate geometry to two equivalent Ba(1) and two equivalent Tb(1) atoms. In the fifth O site, O(5) is bonded in a trigonal planar geometry to one Dy(1) and two equivalent Tb(1) atoms.
