Synthesis and characterization of cobalt SCS pincer complexes

The synthesis and characterization of two Co(II) complexes stabilized by a tridentate SCS pincer ligand are described. Paramagnetic [Co(κ(3)-SCS(CH2)-Et)(2)] and [Co(κ(3)-SCS(CH2)-tBu)(κ(2)-SCS(CH2)-tBu)] were obtained via transmetalation protocol from CoBr(2) and S(C-Br)S(CH2)-R (R = Et, tBu). Oxid...

Sumario:The synthesis and characterization of two Co(II) complexes stabilized by a tridentate SCS pincer ligand are described. Paramagnetic [Co(κ(3)-SCS(CH2)-Et)(2)] and [Co(κ(3)-SCS(CH2)-tBu)(κ(2)-SCS(CH2)-tBu)] were obtained via transmetalation protocol from CoBr(2) and S(C-Br)S(CH2)-R (R = Et, tBu). Oxidation of the latter with [Cp(2)Fe]PF(6) affords the diamagnetic 18 VE complex [Co(κ(3)-SCS(CH2)-tBu)(2)]PF(6). X-ray structures and DFT calculations are presented.
