Reactions of the 1,3-diphosphete complex [Cp'''Co(eta(4)-P(2)C(2)tBu(2))] (Cp''' = Cp(tBu)(3), 1) with Ag[Al{OC(CF3)(3)}(4)] (Ag[TEF]) and [LAu][TEF] (L = (THT)(2), (THT)PPh3) were studied under various reaction conditions. Depending on the stoichiometry of the reactants, reaction time and temperature involved, a selective formation of the monomers, [{(Et2O)Ag}{Cp'''Co(mu,eta(4):eta(1):eta(1)-P(2)C(2)tBu(2))}][TEF] (4) and [Au{Cp'''Co(eta(4):eta(1)-P(2)C(2)tBu(2))}(2)][TEF] (6), the dimer [{(Et2O)Ag}(2){Cp'''Co(mu,eta(4):eta(1):eta(1)-P(2)C(2)tBu(2))}]& sdot;2[TEF] (3), the trimers [Au-3{Cp'''Co(eta(4):eta(1):eta(1)P(2)C(2)tBu(2))}(4)]& sdot;3[TEF] (7) and [(eta(1)-PPh3)(2)Au-3{Cp'''Co(eta(4):eta(1):eta(1)-P(2)C(2)tBu(2))}(2)]& sdot;3[TEF] (8), and the one-dimensional polymer [Ag{Cp'''Co(eta(4):eta(1):eta(1)-P(2)C(2)tBu(2))}](n)[TEF](n) (2) was realized. DFT calculations provided additional insight into the formation of the polymeric species during the assembling process of 2, 3 and 4. All compounds were characterized in the solid state by X-ray crystallography and in solution by multinuclear NMR spectroscopy and mass spectrometry.
