Synthesis and characterization of cobalt SCS pincer complexes.

ABSTRACT: The synthesis and characterization of two Co(II) complexes stabilized by a tridentate SCS pincer ligand are described. Paramagnetic [Co(κ³-SCS^CH2-Et)₂] and [Co(κ³-SCS^CH2-tBu)(κ²-SCS^CH2-tBu)] were obtained via transmetalation protocol from CoBr₂ and S(C-Br)S^CH2-R (R = Et, tBu). Oxidation of the latter with [Cp₂Fe]PF₆ affords the diamagnetic 18 VE complex [Co(κ³-SCS^CH2-tBu)₂]PF₆. X-ray structures and DFT calculations are presented.
