    Addition of trifluoroacetic or trifluoromethanesulfonic acid to solutions of thaIlium(l1l) trifluoroacetate in acetone results in formation of the compounds [TI{CH,C(O)Me},X] (X = CF,CO, l a or CF,SO, 1 b. Compound 1 b reacts in a 1 : 1 ratio with LiCl or KBr giving the halogeno derivatives [TI{CH,C(O)Me},Y] (Y = CI 2a or Br 2b). Compound 2a reacts with [N(PPh,),]CI yielding the anionic complex “(PPh,),] [TI{CH,C(O)Me},CI,] 3. The reaction of 1 b with 2,2‘-bipyridine (bipy) gives [{TI[CH,- C(O)Me],(p-CF,SO,) (bipy)},] 4 in which each thallium atom has a distorted six-co-ordination with the acetonyl ligands in trans positions and two cis positions occupied by two bridging triflate anions.
