The different coordination behavior of the ligand t BuN=Te( μ ‐N t Bu) 2 Te=N t Bu (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⋅⋅⋅Ag interaction.
