The bis(trifluoroacetates) (C5H4R)Co(OCOCF3)2PMe3 (R = H, CHMe2, CMe3) react with P(OMe)3 and NH4PF6 to give the salts (PF6)2 (1 - 3).Their reaction with one mol of NaI leads to PF6 (8 - 10).With an excess of alkalimetal iodide the complexes PF6 (13 - 17) are formed in which the cobaltabis(dimethylphosphonates) behave as chelating ligands towards Li+, Na+, and K+.In the reaction of 13 - 15 (M = Na) with HCl the protonated complexes PF6 (18 - 20) are obtained.Their deprotonation with OH yields the neutral compounds (C5H4R)Co2PMe3 (23 - 25).
