The compound described by Tb2WO6 is Baddeleyite-derived structured and crystallizes in the monoclinic P2_1 space group. There are two inequivalent Tb sites. In the first Tb site, Tb(1) is bonded to one O(1), one O(2), one O(4), two equivalent O(3), and two equivalent O(6) atoms to form a mixture of distorted corner and edge-sharing TbO7 pentagonal bipyramids. In the second Tb site, Tb(2) is bonded to one O(1), one O(4), one O(5), two equivalent O(3), and two equivalent O(6) atoms to form a mixture of distorted corner and edge-sharing TbO7 pentagonal bipyramids. W(1) is bonded in a 6-coordinate geometry to one O(1), one O(4), two equivalent O(2), and two equivalent O(5) atoms. There are six inequivalent O sites. In the first O site, O(1) is bonded in a distorted trigonal planar geometry to one Tb(1), one Tb(2), and one W(1) atom. In the second O site, O(2) is bonded in a 3-coordinate geometry to one Tb(1) and two equivalent W(1) atoms. In the third O site, O(3) is bonded to two equivalent Tb(1) and two equivalent Tb(2) atoms to form a mixture of corner and edge-sharing OTb4 tetrahedra. In the fourth O site, O(4) is bonded in a distorted T-shaped geometry to one Tb(1), one Tb(2), and one W(1) atom. In the fifth O site, O(5) is bonded in a distorted trigonal planar geometry to one Tb(2) and two equivalent W(1) atoms. In the sixth O site, O(6) is bonded to two equivalent Tb(1) and two equivalent Tb(2) atoms to form a mixture of corner and edge-sharing OTb4 tetrahedra. is represented by the CIF file [CIF]
