Abstract By careful oxidation of trans-tetrafluorodichloroosmate(IV) with PbO2/trifluoroacetic acid in dichloromethane the corresponding osmium(V) complex anion rran5 -[OsF4Cl2]- is for med. The X-ray structure determination on a single crystal has been performed of trans-(Et4N)[OsF4Cl2] (triclinic, space group P1̄a = 7.190(5), b = 7.205(5), c = 7.732(5) Å, a = 71.28(1), β = 71.32(1), 7 = 70.76(1)°, Z = 1). Based on the molecular parameters of the X-ray determination the IR and Raman spectra of the complex have been assigned by normal coordi nate analysis. The valence force constants are: fd(OsCl) = 2.13 and fd(OsF) = 3.81 mdyn/Å.
