Osmyl

Osmyl is the name for a moiety found in some chemical compounds of the element osmium. Its systematic name is dioxoosmium(VI). The osmyl structure is found in most compounds where osmium has the +6 oxidation state.

It is often written as OsO2+2, but the simple osmyl cation has never been seen by chemists. Instead, osmyl compounds are coordination complexes where a central O=Os2+=O structure is stabilised by other ligands bonded to the osmium atom. These osmyl complexes normally have square bipyramidal molecular geometry.

Notable osmyl compounds

Potassium osmate contains the anionic osmyl complex OsO2(OH)2−4. This anion has four hydroxide ligands that stabilise the osmyl.

When potassium osmate (or another OsO2(OH4)2− salt) reacts with an acid, the conjugate base can replace hydroxide as a ligand. While these compounds still contain an anionic complex, they are traditionally named like double salts: for example, potassium osmyl chloride (K2OsO2Cl4) or potassium osmyl oxalate (K2OsO2(C2O4)2).

The osmate complex also reacts with ammonium salts because of ammonium's Bronsted acidity. This makes the ammine complex OsO2(NH3)2+4, as seen in osmyl tetra-ammine chloride.
