Abstract
The synthesis and characterization of two Co(II) complexes stabilized by a tridentate SCS pincer ligand are described. Paramagnetic [Co(κ3-SCSCH2-Et)2] and [Co(κ3-SCSCH2-tBu)(κ2-SCSCH2-tBu)] were obtained via transmetalation protocol from CoBr2 and S(C-Br)SCH2-R (R = Et, tBu). Oxidation of the latter with [Cp2Fe]PF6 affords the diamagnetic 18 VE complex [Co(κ3-SCSCH2-tBu)2]PF6. X-ray structures and DFT calculations are presented.

期刊介绍：
"Monatshefte für Chemie/Chemical Monthly" was originally conceived as an Austrian journal of chemistry. It has evolved into an international journal covering all branches of chemistry. Featuring the most recent advances in research in analytical chemistry, biochemistry, inorganic, medicinal, organic, physical, structural, and theoretical chemistry, Chemical Monthly publishes refereed original papers and a section entitled "Short Communications". Reviews, symposia in print, and issues devoted to special fields will also be considered.
