Materials Data on NdHO2 by Materials Project

NdOOH crystallizes in the monoclinic P2_1 space group. The structure is three-dimensional. Nd3+ is bonded in a 7-coordinate geometry to seven O2- atoms. There are a spread of Nd–O bond distances ranging from 2.35–2.65 Å. H1+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 0.99 Å. There are two inequivalent O2- sites. In the first O2- site, O2- is bonded to four equivalent Nd3+ atoms to form a mixture of edge and corner-sharing ONd4 tetrahedra. In the second O2- site, O2- is bonded in a single-bond geometry to three equivalent Nd3+ and one H1+ atom.

Materials Data on Nd(HO)3 by Materials Project

Nd(OH)3 crystallizes in the hexagonal P6_3/m space group. The structure is three-dimensional. Nd3+ is bonded in a 9-coordinate geometry to nine equivalent O2- atoms. There are three shorter (2.52 Å) and six longer (2.54 Å) Nd–O bond lengths. H1+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 0.97 Å. O2- is bonded in a single-bond geometry to three equivalent Nd3+ and one H1+ atom.
