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.
