Abstract: Complex fac-[Fe(CO)3(TePh)3](superscript -) was employed as a "metallo chelating" ligand to synthesize the neutral (CO)3Mn(μ-TePh)3Fe(CO)3 obtained in a one-step synthesis by treating fac-[Fe(CO)3(TePh)3](superscript -) with fac-[Mn+ (CO)3(CH3CN)3](superscript +).It seems reasonable to conclude that the d^6 Fe(Ⅱ) [(CO)3Fe(TePh)3](superscript -)fragment is isolobal with the d^6 Mn(Ⅰ) [(CO)3Mn(TePh)3]2(superscript -)fragment in complex (CO)3Mn(μ-TePh)3Fe(CO)3. Addition of fac[Fe(CO) 3(TePh)3](superscript -)to the CpNi(Ⅰ)(PPh3) in THF resulted in formation of the neutral CpNi(TePh)(PPh3) also obtained from reaction of CpNi(I)(PPh3) and [Na][TePh] in MeOH. This investigation shows that fac[Fe(CO) 3(TePh)3](superscript -) serves as a tridentate metallo ligand and tellurolate ligand-transfer reagent. The study also indicated that the fac-[Fe(CO)3(SePh)3](superscript -)may serve as a better tridentate metallo ligand and chalcogenolate ligand-transfer reagent than fac-[Fe(CO)3(TePh)3](superscript -)in the syntheses of heterometallic chalcogenolate complexes.
