First two pics are of potassium osmate K₂[OsO₂(OH)₄], the latter two are potassium osmyl oxalate K₂[OsO₂(C₂O₄)₂]. Both are hexavalent osmium salts with actual applications.

Potassium osmate finds use in the Sharpless Asymmetric Dihydroxylation, whereby the long and tedious industrial process of converting alkenes such as ethylene into ethylene oxide, and ethylene oxide into ethylene glycol can be accomplished simply, conveniently, efficiently, and safely in a single reaction. Vicinal diols (like ethylene glycol) are very important reagents used in food, medicine, and for creating fabrics, plastics, antifreeze, etc., and an entire century was spent improving and refining the multiple complicated industrial processes necessary just to produce one of them. The asymmetric dihydroxylation method came with a Nobel Prize, and today AD-mixtures are available pre-made for use in labs. (it goes without saying, this reaction can't be scaled up to industrial size due to the rarity of osmium and probably because it might not scale safely either. The OMEGA process developed by Shell is still being used).

Potassium osmyl oxalate containing synthetic Os-191 began use for radionuclide angiocardiography in children's hospitals in the 1980's. In 2012 a paper was published investigating a possible improved production of this method using potassium hexachloroosmate (which I've made previously).
