Title: [(MeCN)3Co(C2F5)3]: A Versatile Precursor to Cobalt(III) Perfluoroethyl Complexes

Abstract

The air-stable [fac-(MeCN)3Co(C2F5)3] (1) was prepared through the reaction of cobalt(II) bromide with [Me3Si-C2F5] and AgF. Upon reaction of 1 with wet pyridine, the unexpected product [fac-(H2O)3Co(C2F5)3·6 pyridine] (2) was formed in which water coordinates to cobalt instead of pyridine, and the pyridines form short contacts with each of the hydrogen atoms in the bound water molecules. Facile exchange of the bound acetonitrile ligands in 1 with terpyridine (tpy) and bipyridine (bpy) did occur, however, affording [(tpy)Co(C2F5)3] (5) and [(bpy)Co(C2F5)3(MeCN)] (6) in high yields.
