The betain-like compound S2CC(PPh3)2 (1), which is obtained from CS2 and the double ylide C(PPh3)2, reacts with [Co2(CO)8] and [Mn2(CO)10] in THF to afford the salt-like complexes [CoS2CC(PPh3)2}3][Co(CO)4]3 (2) and [(CO)4MnS2CC(PPh3)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−I and
