N2 - Reactions of the complexes [Mol3(CO)2(?5-C5H5)] and [W(SC6F5)3(CO)(?5-C 5H5)] with M'(SC6F5) give Cs[Mo(SC6F5)4(?5-C 5H5)], M'[W(SC6F5)4(?5-C 5H5)] (M' = Cs, Rb or K) and solvated derivatives (M = Mo or W) M'[W(SC6F5)4(?5-C 5H5)]·nthf (M' = Li, n = 4; or Na, n = 1); 133Cs and 19F NMR studies of Cs[M(SC6F5)4(?5-C 5H5)] reveal co-ordination between the Cs+ and the organometallic anion and Cs-F coupling involving four o-fluorines of the SC6F5 groups, J(Cs-F) ˜ 58 Hz.
