AbstractThe inter-triangular diphosphine bridge in [AuMn2(CO)8(μ-PPh2)]2(μ-P-P) turns into an intra-triangular one as it undergoes amine-oxide-promoted decarbonylation to give (P-P)-AuMn2(CO)7(μ-PPh2) (P-P = Ph2P-X-PPh2; X = (CH2)n, Fe(C5H4)2; n = 1-4) in the presence of the corresponding free diphosphine. The resultant triangular cluster contains a heterometallic Au-Mn bond overbridged by all common diphosphines attempted, including dppf (X = Fe(C5H4)2) and dppp (n = 3). The Au-Mn bond supported by dppf (2.6797(7) Å) is shorter than that supported by dppe (n = 2) (2.756(2) Å) or dppp (2.7643(4) Å).
