摘要

The cis-[Mn(CO)4(TePh)2]-, similar to bidentate ligand PhTe(CH2)3, acts as a "chelating metalloligand" for the synthesis of metallic tellurolate compounds. The reaction of cis-[Mn(CO)4(TePh)2]- with BrMn(CO)5 in THF leads to a mixture of products [(CO)3BrMn(μ-TePh)2Mn(CO)4]- (1) and Mn2(μ-TePh)2(CO)8 (2). Complex 1 crystallizes in the triclinic space group P1̄ with a = 11.309(3) Å, b = 14.780(5) Å, c = 19.212(6) Å, α = 76.05(3)° β = 72.31(3)°, γ = 70.41(3)°, V = 2848(2) Å3, Z = 2. Final R = 0.034 and Rw = 0.035 resulting from refinement of 10021 total reflections with 677 parameters. Dropwise addition of (MeTe)2 to a solution of [Me3O][BF4] in CH3CN leads to formation of [Me2TeTeMe][BF4], a potential MeTe+ donor ligand. In contrast to oxidative addition of diphenyl ditelluride to [Mn(CO)5]- to give cis-[Mn(CO)4(TePh)2]- which was thermally transformed into [(CO)3Mn(μ-TePh)3Mn(CO)3]-, reaction of [Mn(CO)5]- with [Me2TeTeMe]+ proceeded to give the monomeric species MeTeMn(CO)5 as initial product which was then dimerized into Mn2(μ-TeMe)2(CO)8 (4).
