- 中文摘要: The cis- [ Mn(CO)/sub 4/(TePh)/sub 2/ ] /sup -1/, similar to bidentate ligand PhTe(CH/sub 2/)/sub 3/TePh, acts as a "chelating metalloligand" for the synthesis of metallic tellurolate compounds. The reaction of cis- [ Mn(CO)/sub 4/(TePh)/sub 2/ ] / sup -/ with BrMn(CO)/sub 5/ in THF leads to a mixture of products [ (CO)/sub 3/ BrMn(.mu.-TePh)/sub 2/Mn(CO)/sub 4/ ] /sup -/ (1) and Mn/sub 2/(.mu.-TePh)/sub 2/(CO)/sub 8/. Complex 1 crystallizes in the triclinic space group P.1bar. with a=11.309(3) .ANG., b=14.780(5).ANG., c=19.212(6).ANG.,.alpha.=76.05(3).degree., .beta.=72.31(3).degree.,.gamma.=70.41(3).degree., V=2848(2).ANG./sup 3/, Z=2. Final R=0.034 and R/sub w/=0.035 resulting from refinement of 10021 total reflections with 677 parameters. Dropwise addition of (MeTe)/sub 2/ to a solution of [ Me/sub 3/O ] [ BF/sub 4/ ] in CH/sub 3/CN leads to formation of [ Me/sub 2/TeTeMe ] [ BF/sub 4/ ] , a potential MeTe/sup +/ donor ligand. In contrast to oxidative addition of diphenyl ditelluride to [ Mn(CO)/sub 5/ ] /sup -/ to give cis- [ Mn(CO)/sub 4/(TePh)/sub 2/ ] /sup -/ which was thermally transformed into [ (CO)/sub 3/Mn(.mu.-TePh)/sub 3/Mn(CO)/sub 3/ ] /sup -/, reaction of [ Mn(CO)/sub 5/] /sup -/ with [ Me/sub 2/TeTeMe ] /sup +/ proceeded to give the monomeric species MeTeMn(CO)/sub 5/ as initial product which was then dimerized into Mn/sub 2/(.mu.-TeMe)/sub 2/(CO)/sub 8/.
