Coinage Metal Complexes of a Tellurium Diimide: cis-->trans Isomerization and Metal-Metal Interactions.
The different coordination behavior of the ligand tBuN=Te(µ-NtBu)(2)Te=NtBu (L) towards Cu(+) and Ag(+) results from a cis-->trans isomerization. The two Cu(+) ions in [Cu(2)L(3)](2+) (shown schematically) bridge trans and cis isomers of the ligand, whereas the Ag(+) ions in [Ag(2)L(2)](2+) link two trans ligands and exhibit a weak Ag small middle dot small middle dot small middle dotAg interaction.
