In this report, synthetic routes to [(MeCN)3Co­(CF3)3], [Co­(MeCN)6]­[PF6]2, [(MeCN)4Co­(CF3)2]­[PF6], [(MeCN)2(py)­Co­(CF3)3], [(MeCN)­(py)2Co­(CF3)3], and [(MeCN)4Co­(C4F8)]­[PF6] are described. The unusual [(py)2(CF3)2Co­(μ-CH2CN)]2 has also been identified as a decomposition product of [(py)2(MeCN)­Co­(CF3)3]. The aforementioned compounds, all of which have been characterized by X-ray crystallography, are expected to serve as useful precursors to cobalt trifluoromethyl- and C4F8-containing derivatives.
