The reactions of tertiary arsines and diarsines with a mixture of OsO4, concentrated HCl, and ethanol at low temperatures produce the dioxo-osmium(VI) complexes (L=AsEt3, AsMe2Ph, or AsPh3) and .The corresponding reactions at higher temperatures lead to mixtures containing Os^IV complexes and chloro complexes of Os^III and Os^IV.The diphosphine complexes are prepared similarly, but are very difficult to obtain pure, and the bromo complexes (L-L)= diphosphine or diarsine> are obtained from OsO4, concentrated HBr, EtOH, and L-L.NNN'N'-Tetramethylenediamine (tmen) produces , and has been characterised as a minor by-product in the case of X=Cl.Bis-ligand complexes have been characterised by i.r., u.v.-visible, (1)H, and (31)P n.m.r. spectroscopy and microanalysis.Decomposition in solution is suggested to involve oxygen-atom transfer from the OsO2(2+) group to the neutral ligand.The properties and stabilities of the complexes are discussed and the ease of oxidation of the neutral ligands is suggested to be a major factor determining relative stabilities.
