Synthesis and characterization of cobalt SCS pincer complexes.

Unlabelled: The synthesis and characterization of two Co(II) complexes stabilized by a tridentate SCS pincer ligand are described. Paramagnetic [Co(κ-SCS-Et)] and [Co(κ-SCS-Bu)(κ-SCS-Bu)] were obtained via transmetalation protocol from CoBr and S(C-Br)S-R (R = Et, Bu). Oxidation of the latter with [CpFe]PF affords the diamagnetic 18 VE complex [Co(κ-SCS-Bu)]PF. X-ray structures and DFT calculations are presented.
