The first carbonyl compound of a transition metal in the oxidation state +6 was obtained by reductive carbonylation of OsO 4 in SbF 5 . Through the use of extensive IR, NMR, and UV/Vis spectroscopic studies as well as density functional calculations it was determined that the trans ‐[OsO 2 (CO) 4 ] 2+ cation adopts the octahedral structure shown in the picture with trans oxygen atoms.
