YbOOH crystallizes in the tetragonal P-42_1m space group. Yb(1) is bonded in a 7-coordinate geometry to two equivalent O(1), two equivalent O(2), and three equivalent O(3) atoms. H(1) is bonded in a single-bond geometry to one O(3) atom. There are three inequivalent O sites. In the first O site, O(1) is bonded to four equivalent Yb(1) atoms to form a mixture of distorted edge and corner-sharing OYb4 tetrahedra. In the second O site, O(2) is bonded to four equivalent Yb(1) atoms to form a mixture of edge and corner-sharing OYb4 tetrahedra. In the third O site, O(3) is bonded in a distorted single-bond geometry to three equivalent Yb(1) and one H(1) atom.
YbOOH crystallizes in the tetragonal P-42_1m space group. Yb(1) is bonded in a 7-coordinate geometry to two equivalent O(1), two equivalent O(2), and three equivalent O(3) atoms. Both Yb(1)-O(1) bond lengths are 2.40 Å. Both Yb(1)-O(2) bond lengths are 2.37 Å. There is one shorter (2.32 Å) and two longer (2.35 Å) Yb(1)-O(3) bond lengths. H(1) is bonded in a single-bond geometry to one O(3) atom. The H(1)-O(3) bond length is 0.98 Å. There are three inequivalent O sites. In the first O site, O(1) is bonded to four equivalent Yb(1) atoms to form a mixture of distorted edge and corner-sharing OYb4 tetrahedra. In the second O site, O(2) is bonded to four equivalent Yb(1) atoms to form a mixture of edge and corner-sharing OYb4 tetrahedra. In the third O site, O(3) is bonded in a distorted single-bond geometry to three equivalent Yb(1) and one H(1) atom.
