The crystal structure described by TmOOH crystallizes in the monoclinic P2_1/c space group. Tm(1) is bonded to three equivalent O(1) and three equivalent O(2) atoms to form a mixture of corner and edge-sharing TmO6 octahedra. The corner-sharing octahedral tilt angles range from 54-58°. H(1) is bonded in a distorted single-bond geometry to one O(1) and one O(2) atom. There are two inequivalent O sites. In the first O site, O(1) is bonded to three equivalent Tm(1) and one H(1) atom to form a mixture of distorted corner and edge-sharing OTm3H tetrahedra. In the second O site, O(2) is bonded in a distorted single-bond geometry to three equivalent Tm(1) and one H(1) atom. is represented by the CIF file [CIF]
