Although the triple-decker complex [Cp*Fe(µ,η⁵:η⁵-P₅)Mo(CO)₃] ( 2 ) was first reported 26 years ago, its reactivity has not yet been explored. Herein, we report a new high-yielding synthesis of 2 and the isolation of its new polymorph ( 2' ). In addition, we study its reactivity towards Ag I and Cu I ions. The reaction of 2 with Ag[BF₄] selectively produces the coordination compound [Ag{Cp*Fe(µ,η⁵:η⁵-P₅)Mo(CO)₃}₂][BF₄] ( 3 ). Its reaction with Ag[TEF] and Cu[TEF] ([TEF] - = [Al{OC(CF₃)₃}₄] - ) leads to the selective formation of the complexes [Ag{Cp*Fe(µ,η⁵:η⁵-P₅)Mo(CO)₃}₂][TEF] ( 4 ) and [Cu{Cp*Fe(µ,η⁵:η⁵-P₅)Mo(CO)₃}₂][TEF] ( 5 ), respectively. The X-ray structures of compounds 3 ⁻ 5 each show an M I ion (M I = Ag I , Cu I ) bridged by two P atoms from two triple-decker complexes ( 2 ). Additionally, four short M I ···CO distances (two to each triple-decker complex 2 ) participate in stabilizing the coordination sphere of the M I ion. Evidently, the X-ray structure for compound 3 shows a weak interaction of the Ag I ion with one fluorine atom of the counterion [BF₄] - . Such an Ag···F interaction does not exist for compound 4 . These findings demonstrate the possibility of using triple-decker complex 2 as a ligand in coordination chemistry and opening a new perspective in the field of supramolecular chemistry of transition metal compounds with phosphorus-rich complexes.
