✦ Synopsis

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) (shown schematically) bridge trans and cis isomers of the ligand, whereas the Ag(+) ions in Ag(2)L(2) link two trans ligands and exhibit a weak Ag small middle dot small middle dot small middle dotAg interaction.
