Materials Data on OsO4 by Materials Project

OsO4 is Silicon tetrafluoride-like structured and crystallizes in the monoclinic C2 space group. The structure is zero-dimensional and consists of two OsO4 clusters. Os8+ is bonded in a tetrahedral geometry to four O2- atoms. All Os–O bond lengths are 1.72 Å. There are two inequivalent O2- sites. In the first O2- site, O2- is bonded in a single-bond geometry to one Os8+ atom. In the second O2- site, O2- is bonded in a single-bond geometry to one Os8+ atom.

Materials Data on OsO2 by Materials Project

OsO2 is Hydrophilite structured and crystallizes in the tetragonal P4_2/mnm space group. The structure is three-dimensional. Os4+ is bonded to six equivalent O2- atoms to form a mixture of corner and edge-sharing OsO6 octahedra. The corner-sharing octahedral tilt angles are 53°. There is two shorter (1.97 Å) and four longer (2.02 Å) Os–O bond length. O2- is bonded in a trigonal planar geometry to three equivalent Os4+ atoms.
