A biased bimetallic Fe-Fe complex Cp*Fe(dppe)(C ≡ CFc) (1) was synthesized from FcC ≡ CH (Fc=C5H4FeC5H5)and Cp*Fe(dppe)C1 (Cp*=C5Me5). Its one-electron oxidation species [Cp*Te(dppe)(C≡ CFc)][PF6] (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=1.26074(4) nm, c=1.649 89(5) nm,fined to R1=0.038 4, wR2=0, 1000. CCDC: 234893.
