Materials Data on H12OsC4NO4F by Materials Project
OsO4FN(CH3)4 is Silicon tetrafluoride-derived structured and crystallizes in the orthorhombic Aem2 space group. The structure is zero-dimensional and consists of four tetramethylammonium molecules and four OsO4F clusters. In each OsO4F cluster, Os2- is bonded in a distorted trigonal bipyramidal geometry to four O2- and one F1- atom. There is three shorter (1.74 Å) and one longer (1.75 Å) Os–O bond length. The Os–F bond length is 2.14 Å. There are three inequivalent O2- sites. In the first O2- site, O2- is bonded in a single-bond geometry to one Os2- atom. In the second O2- site, O2- is bonded in a single-bond geometry to one Os2- atom. In the third O2- site, O2- is bonded in a single-bond geometry to one Os2- atom. F1- is bonded in a distorted single-bond geometry to one Os2- atom.
