The reactions of the zerovalent carbonyl complexes Mo(CO)6 and Mo(CO)4(bipy) with a series of uninegative bidentate (X,Y)-donor ligands (X,Y = xanthates, dithiocarbamates, o-aminophenoxide, o-aminothiophenoxide, 2-picolinate and thioacetate) lead to new anionic tetracarbonyl complex anions 0(X,Y)(CO)4>^-.These anions, which can be isolated as their tetraphenylphosphonium salts, contain the (X,Y)-ligand as a bidentate group.In the case of (X,Y) = monothioaceate the decarbonylated species II(TA)3> is formed.The reactions of the new complexes with allyl bromide and methyl iodide are described.
