The trinuclear clusters Fe3(CO)9(H)(SR) (A), first described by Haines et al., are proton acids with pKS values between 3 and 4, thus giving stable salts containing - anions (2 - 4).The influence of the hydrido bridge present in A on the geometry of the cluster framework is studied by comparison of X-ray results on A and on the anion -.Up to three carbonyl groups of A are substituted by donor ligands E(C6H5)3 (E = P, As, Sb) under thermal or photochemical conditions (5 - 9).The geometry of the substitution products is inferred from spectroscopic data and from two X-ray analyses.
