Effect of the Osmium Forms and Their Transformation in Different Media with Formation of Cruds
Engineered ScienceAbout 70% of osmium passes into the process gas mixture (from electric furnace and converter gases) during sulfide copper raw material processing. Of the osmium-187 isotope in copper concentrate, 45–57% accumulates in the sulfuric acid wash during ...

Cyclometalated Osmium Compounds and beyond: Synthesis, Properties, Applications
Molecules, 2021 The synthesis of cyclometalated osmium complexes is usually more complicated than of other transition metals such as Ni, Pd, Pt, Rh, where cyclometalation reactions readily occur via direct activation of C–H bonds.

Chemistry of osmium in N2P2Br2 coordination sphere
, 1999 A family of three mixed-ligand osmium complexes of type [Os(PPh3)2(N-N)Br2], where N-N=2,2′-bipyridine (bpy), 4,4′-dimethyl-2,2′-bipyridine (Me2bpy) and 1,10-phenanthroline (phen), have been synthesized and characterized.

Arene-Osmium(II) Complexes in Homogeneous Catalysis
Inorganics, 2021 Although the application of arene-osmium(II) complexes in homogeneous catalysis has been much less studied than that of their ruthenium analogues, different works have shown that, in some instances, a comparable or even superior effectiveness can be ...
