Osmium telluride

The reaction of tellurium with osmium-carbyne complexes1 or with osmium-methylene complexes2, or of sodium hydrogen telluride with iodomethyl(iodo)-osmium complexes3 produced tellurolato-osmium compounds. 

Carbon monotelluride is only known as a ligand coordinated to osmium1,2 or molybdenum3. Air-stable carbonyldichloro(telluracarbonyl)bis triphenylphosphane]osmium(II) was obtained from carbonyldichloro(dichlorocarbene)bis[triphenylphosphane]osmi-um(III) and sodium hydrogen telluride in benzene1,2.
