Unprecedented N‐Inserted Disulfide Ligand Stabilized by Coordination to the Electropositive Co III Center

The reaction of Co II and 2,2′‐dipyridyldisulfide (PySSPy) in the presence of azide produced a peculiar monomeric complex [Co III (PyS)(PyS‐N‐SPy)(N 3 )] ( 1 ). In this reaction, redox chemistry takes place, which is associated mainly with the oxidation of Co II to Co III and the reduction of PySSPy...

Description
Summary:The reaction of Co II and 2,2′‐dipyridyldisulfide (PySSPy) in the presence of azide produced a peculiar monomeric complex [Co III (PyS)(PyS‐N‐SPy)(N 3 )] ( 1 ). In this reaction, redox chemistry takes place, which is associated mainly with the oxidation of Co II to Co III and the reduction of PySSPy. During the reaction, the azide ion decomposes and donates a nitrogen atom to PySSPy. The crystal structure of 1 provides evidence that the unusual, N‐inserted ligand PyS‐N‐SPy can be stabilized through coordination to the electropositive Co III ion. (© Wiley‐VCH Verlag GmbH & Co.
