Abstract
The reaction of CoII and 2,2′-dipyridyldisulfide (PySSPy) in the presence of azide produced a peculiar monomeric complex [CoIII(PyS)(PyS-N-SPy)(N3)] (1). In this reaction, redox chemistry takes place, which is associated mainly with the oxidation of CoII to CoIII 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 CoIII ion. (© Wiley-VCH Verlag GmbH & Co.
