Osmium(III) chloride is an inorganic chemical compound of osmium metal and chlorine with the chemical formula OsCl3.[1][2]

Synthesis

Osmium(III) chloride can be made by a reaction of chlorine with osmium:

2Os + 3Cl2 → 2OsCl3

It can also be made by heating of osmium(IV) chloride:

2OsCl4 → 2OsCl3 + Cl2

Physical properties

Sample of commercial osmium trichloride trihydrate.

Osmium(III) chloride forms black-brown crystals.[3]

Osmium(III) chloride forms a hydrate of the composition OsCl3·3H2O with dark green crystals.[4]

Uses and reactions

Osmium(III) chloride hydrate is used as a precursor material for the production of dichlorodihydridoosmium complex compounds and other compounds.[5]

It is the precursor to a variety of arene complexes.[6]
