The material described by YHO2 crystallizes in the monoclinic P2_1/m space group. Y(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 Y(1) atoms to form a mixture of edge and corner-sharing OY4 tetrahedra. In the second O site, O(2) is bonded in a single-bond geometry to three equivalent Y(1) and one H(1) atom. is represented by the CIF file [CIF]
