The material described by LaOOH crystallizes in the monoclinic P2_1/m space group. La(1) is bonded in a 7-coordinate geometry to three equivalent O(2) and four equivalent O(1) atoms. H(1) is bonded in a single-bond geometry to one O(2) atom. There are two inequivalent O sites. In the first O site, O(1) is bonded to four equivalent La(1) atoms to form a mixture of corner and edge-sharing OLa4 tetrahedra. In the second O site, O(2) is bonded in a single-bond geometry to three equivalent La(1) and one H(1) atom. is represented by the Crystallographic Information File (CIF) [CIF]
