Summary:A group of dihalogenobis complexes of the type [OsX2(HA)(A)] (1) and mixed-tris chelates of types [Os(A)(L)(2)]ClO4.H2O (2), [Os(A)(Q)(2)] (3) and [Os(A)(Q)(2)]ClO4.H2O (4) [where X=Cl or Br; HA=camphor-quinone monooxime; L = 2-(arylazo)pyridines and HQ=quinolin-8-ol and its derivative] have been prepared by distinctly different synthetic routes and characterized by microanalytical, IR, EPR, UV-Vis and electro-chemical results. Reversible/nearly-reversible osmium(III)osmium(II) and osmium(IV)-osmium(III) couples are invariably seen in all the complexes.
