Abstract

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 R_w = 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).
