TbGdPO6PO2 crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one dioxaphosphirane molecule and one TbGdPO6 cluster. In the TbGdPO6 cluster, Tb(1) is bonded in a distorted L-shaped geometry to one O(1), one O(2), one O(7), and one O(8) atom. The Tb(1)-O(1) bond length is 1.46 Å. The Tb(1)-O(2) bond length is 2.61 Å. The Tb(1)-O(7) bond length is 1.46 Å. The Tb(1)-O(8) bond length is 2.61 Å. Gd(1) is bonded in a distorted single-bond geometry to one P(2) and one O(2) atom. The Gd(1)-P(2) bond length is 0.34 Å. The Gd(1)-O(2) bond length is 1.17 Å. P(2) is bonded in a distorted single-bond geometry to one Gd(1), one O(2), and one O(3) atom. The P(2)-O(2) bond length is 1.16 Å. The P(2)-O(3) bond length is 1.39 Å. There are six inequivalent O sites. In the first O site, O(1) is bonded in a single-bond geometry to one Tb(1) atom. In the second O site, O(2) is bonded in a 3-coordinate geometry to one Tb(1), one Gd(1), and one P(2) atom. In the third O site, O(3) is bonded in a distorted single-bond geometry to one P(2) and one O(5) atom. The O(3)-O(5) bond length is 1.49 Å. In the fourth O site, O(5) is bonded in a single-bond geometry to one O(3) atom. In the fifth O site, O(7) is bonded in a single-bond geometry to one Tb(1) atom. In the sixth O site, O(8) is bonded in a distorted single-bond geometry to one Tb(1) atom.
