Reactions of cis-[(super)t BuNTe(mu-N (super)t Bu)] (sub)2 with CF (sub)3 SO (sub)3 Me and M[O (sub)3 SCF (sub)3] (M = Ag, Cu): chelation, cis (results in) trans isomerization, and the spirocyclic ligand [(super)t BuNTe(mu-N (super)t Bu) (sub)2 Te(mu-O)] (sub)2

Research has been conducted on the tellurium diimide dimer coordination complexes. Mono- and dimethylation of the complexes have been demonstrated via (super)1 H and (super)125 Te NMR spectroscopy.
