摘　　要：A biased bimetallic Fe-Fe complex Cp*Fe(dppe)(C≡CFc) (1) was synthesized from FcC≡CH (Fc=C5H4FeC5H5) and Cp*Fe(dppe)Cl (Cp*=C5Me5). Its one-electron oxidation species [Cp*Fe(dppe)(C≡CFc)] (1a) was also prepared and the spectroscopic properties of 1a was studied. The single-crystal X-ray diffraction analysis of 1 shows that ferrocenylacetylene is bonded at the terminal carbon to the iron center in the Cp*Fe(dppe) part. Crystallographic data for 1: monoclinic, space group C2/c, with a=4.067 65(14) nm, b=1.260 74(4) nm, c=1.649 89(5) nm, β=104.387(10)°, V=8.195 7(5) nm3, Z=8, Dc=1.354 g·cm-3, F(000)=3 512, μ=0.822 mm-1. The structure was refined to R1=0.038 4, wR2=0.100 0. CCDC: 234893.A biased bimetallic Fe-Fe complex Cp*Fe(dppe)(C≡CFc) (1) was synthesized from FcC≡CH (Fc=C5H4FeC5H5) and Cp*Fe(dppe)Cl (Cp*=C5Me5).
