Abstract

Simple reactions of K2OsCl6 with a cis-1,2-bis(diphenylphosphino)ethene or 1,2-bis(diphenylphosphino)benzene in 1:2.05 ratio performed in refluxing DMF solution lead to the formation of the osmium(II) complexes with formulae of Os(P ∩ P)(CO)2Cl2. The obtained complexes were characterized by means of IR and 31P NMR spectroscopic techniques and their molecular structures were confirmed by X-ray investigations. Due to lability of CO and Cl− within Os(P ∩ P)(CO)2Cl2 molecules both of the investigated complexes can be converted to luminescent [Os(N ∩ N)(P ∩ P)(CO)Cl]+ species.
