solution and the solid state. The dibutylstannyl derivative reacted with BuLi in THF to give a pentaorganostannate, which was characterized by means of 119Sn NMR and UV-vis spectroscopies. Their optical properties were analyzed with TD-DFT calculations. The first excitation of dialkylstannyl derivatives is assigned to the π-π* excitation, and an intersystem crossing from the relaxed S1 state to a triplet state

1-(9-anthyltelluro)enyne. Oxidation and bromination of the telluride yielded telluroxide and hypervalent Te,Te-dibromide, respectively. Their structures were determined by X-ray crystallography. Unlike its highly fluorescent sulfur and selenium congeners, the telluride is barely fluorescent in solution at room temperature due to the heavy-atom effect of tellurium. The telluride displayed temperature-dependent
