TL;DR: The reaction between osmium metal and fluorine gas had been reported in 1913 by Ruff and Tschirch to yield three products, OBF/sub 4, Os F/sub 6, and Os F /sub 8/ as mentioned in this paper, which led to the formation of only the most volatile of these, the yellow solid that they identified as Osmium octafluoride.
Abstract: The reaction between osmium metal and fluorine gas had been reported in 1913 by Ruff and Tschirch to yield three products, OBF/sub 4/, OsF/sub 6/, and OsF/sub 8/. A repetition of their synthesis led to the formation of only the most volatile of these, the yellow solid that they identified as osmium octafluoride. Our measurements of the melting point, 32.1 deg , and the boiling point, 45.9 deg , establish the identity of tbe product with their octafluoride. However, the molecular weight determinations and chemical analysis show the composition of this compound to be OsF/sub 6/ rather than OsF/sub 8/. This conclusion is also supported by x-ray diffraction measuremsnts and infrared and Raman spectroscopy. It appears very likely that the compound known now for many years as osmium octafluoride is in fact osmium hexafluoride and that the compound previously called OsF/sub 4/ also was identified incorrectly.

TL;DR: Osmium pentachloride, a new binary chloride of osmium, has been prepared by the reaction of Osmium hexafluoride with excess boron trichloride below room temperature as discussed by the authors.
Abstract: Osmium pentachloride, a new binary chloride of osmium, has been prepared by the reaction of osmium hexafluoride with excess boron trichloride below room temperature. The pentachloride is isomorphous with rhenium pentachloride and has been characterized by x-ray methods, by infrared and uv-visible spectroscopy, and by magnetic and other physical procedures. Some reactions of the pentachloride are also reported in this paper. Reaction of osmium hexafluoride with carbon tetrachloride, known to be less effective than boron trichloride in halogen-exchange reactions, produces a nonstoichiometric product which probably contains several mixed halides of osmium. 3 figures, 5 tables.

TL;DR: In this paper, a discussion of the optical absorption spectrum and the susceptibility of OsF6 is devoted to a discussion, where two 5d electrons, which move in a ligand field of octahedral symmetry, are responsible for the magnetic and optical properties of the molecule.
Abstract: This paper is devoted to a discussion of the optical absorption spectrum and the susceptibility of OsF6. It is assumed that two 5d electrons, which move in a ligand field of octahedral symmetry, are responsible for the magnetic and optical properties of the molecule. The calculated positions of the energy levels depend on the strength of the ligand field, the Coulomb integrals and the spin‐orbit coupling constant. These quantities are treated as parameters. If they are given appropriate values, excellent agreement with observed energy level positions is obtained. The calculated susceptibility is also in good agreement with experimental values. In order to fit the magnetic data it is necessary to assume that the orbital reduction factor is approximately 0.7.

TL;DR: Xenon and Iridiumhexafluoride react at temperatures above room temperature forming XeF+IrF6 - forming a blue charge transfer complex that cannot be isolated as a solid.
Abstract: Xenon and Iridiumhexafluoride react at temperatures above room temperature forming XeF+IrF6–. In presence of SbF5 FXe+IrSbF11– is formed. Xenon and Osmiumhexafluoride form in solution a blue charge transfer complex that cannot be isolated as a solid.

TL;DR: Osmium hexafluoride combines with bromine to form Br2OsF6 as discussed by the authors, and solutions of OsF6 in liquid chlorine are strongly blue or blue violet in colour, and charge transfer interactions are indicated.
