Materials Data on HoHO2 by Materials Project
HoOOH crystallizes in the orthorhombic Pnma space group. The structure is three-dimensional. Ho3+ is bonded to six O2- atoms to form a mixture of distorted edge and corner-sharing HoO6 octahedra. The corner-sharing octahedral tilt angles are 59°. There are a spread of Ho–O bond distances ranging from 2.20–2.40 Å. H1+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 1.00 Å. There are two inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted single-bond geometry to three equivalent Ho3+ and one H1+ atom. In the second O2- site, O2- is bonded in a trigonal planar geometry to three equivalent Ho3+ atoms.
