Phenylseleninate-Connected Telluroxane Clusters.

Hydrolysis of PhTeI in the presence of sodium phenylseleninate and M ions (M = Y, Nd, Ce) gives well-defined, bowl-shaped telluroxane clusters. Each of the two half-spheres of the compositions [(PhTe){ML}O] ({ML} = {Y(NO)(HO)} (), {Nd(NO)(HO)} (), or {Ce(NO)} ()) are connected by two (compound ) or four (compounds and ) PhSeO bridges. The resulting chalcogenoxane spheres have internal volumes of approximately 1500 Å.
