The derivative chemistry of the clusters H2Fe3(CO)9PR, HFe3(CO)9PR-, and Fe3(CO)9PR2- with R = Me, t-Bu, Ph, Tol was investigated.It could be shown by the formation of the anions HFe3(CO)9PR- from Fe3(CO)112- and Cl2PR that the clusters are accessible without the inconvenience due to the odour of the reagrents H2PR.As an intermediate of the new synthesis reaction the anion HFe2(CO)7-μ-PMe-Fe(CO)4- was obtained and characterized by a structure analysis of its PPN salt (5a).The high acidity of the clusters H2Fe3(CO)9PR resulted in their easy deprotonation.With main group element dihalogen compounds EHal2 (E = PPh, PTol, AsMe, SnMe2) and K2Fe3(CO)9PR (R = Ph, Tol) the doubly bridged clusters Fe3(CO)9(μ3-PR)(μ3-E) (E = PPh, PTol, AsMe) and Fe3(CO)9(μ3-PR)(μ2-SnMe2) were formed.With the noble metal regants n with M = Cu, Ag, Au cluster expansion was possible which starting from the anionic Fe3P clusters led to a series of new compounds with PFe3M and PFe3M2 frameworks.
