Tellurium-bridged complexes

Telluroacetone coordinated to manganese was obtained from a tellurium-bridged dinuclear manganese complex and dimethyldiazomethane4. 

Complexes with sulfur, selenium, and tellurium bridging ligands... 

The dimeric tellurium diimides can act as chelating or bridging ligands. In the cis,exo,exo conformation, the formation of A. TV -chclated complexes is... 

The situation close to that described above for sulfur is characteristic for the chal-cogenide elements. Atomic selenium [1,26,82-86] and tellurium [86] are part of di-, tri-, and polynuclear clusters, while diatomic molecules of these elements, when acting as ligands, have mostly a bridge function 52. Examples of di- and trinuclear monochalcogenide compounds are the complexes 53 and 54 [82-85] ... 

Complexes 56 [87] and 57 [82-85] are of considerable interest. During the formation of the first compound, both atomic and molecular tellurium participate simultaneously in the second one, Te2 carries out the functions of a-bridge and 7t-donor ligand [82-85], The cases are known when two diselenide bridges (for example, 58) and pentaselenide rj1 -terminal (59) ligation occurs [82-85] ... 

The reaction of bromopentacarbonylmanganese(I) and of pentacarbonylchlororhenium(I) with bis[trimethylstannyl] tellurium produced dimeric carbonyl complexes with two trimethylstannyltelluro groups bridging the metal centers5.
