Formation of the salt-like complexes [Co{S2CC(PPh 3)2}3][Co(CO)4]3 and [(CO)4Mn{S2CC(PPh3)2}][Mn(CO) 5] from the reaction of the related carbonyl compounds with S 2CC(PPh3)2

The betain-like compound S2CC(PPh3)2 (1), which is obtained from CS2 and the double ylide C(PPh 3)2, reacts with [Co2(CO)8] and [Mn2(CO)10] in THF to afford the salt-like complexes [Co{S2CC(PPh3)2}3][Co(CO) 4]3 (2) and [(CO)4Mn{S2CC(PPh 3)2}][Mn(CO)5] (3), respectively, in good yields. At both d6 cations 1 acts as a chelating ligand. Disproportionation reactions from formal Co0 into CoIII and Co-1 and from Mn0 into Mn1 and Mn -1 occurred with the removal of four or one carbonyl groups, respectively. The crystal structures of 2·5.5THF and 3·2THF are reported, which show a shortening of the C-C bond in the ligand upon complex formation. The compounds are further characterized by 31P NMR and IR spectroscopy.
