“…The starting parameters in the least-squares refinement were those of Siegel, Viste, Hoekstra & Tani (1972). The deuterium position was estimated by us to be at (0.28, 0.51, 0.09) assuming a bifurcated hydrogen bond of the O(2)-D group with O(1) and 0(5).…”

“…The uranium and oxygen locations were determined recently by Siegel, Viste, Hoekstra & Tani (1972), in a single crystal X-ray diffraction study, using 756 independent reflexions. The two crystallographically independent uranium atoms in the triclinic structure were surrounded by octahedra and pentagonal dipyramidal configurations of oxygens.…”

The deuterium atom in the deuterium triuranate crystal, D2U3010, has been located by the method of powder neutron diffraction and is attached to the 0(2) atom in the pentagonal ring of the pentagonal bipyramid around U(2), as predicted by earlier workers. It forms a bifurcated deuterium bond with the O(1) atom of a neighbouring octahedron around U(1) and the 0(5) atom of a neighbouring pentagonal bipyramid. The O(2)-O(1) and 0(2)-0(5) hydrogen bond distances are 2.76 (6) and 2"76 (7)/~ and the hydrogen bond angles 101(4) ° and 133(3) ° respectively. The hydroxyl O-D distance is 1.09 (4)/1,.
