Phenylseleninate-Connected Telluroxane Clusters.

ABSTRACT: Hydrolysis of PhTeI₃ in the presence of sodium phenylseleninate and M³⁺ ions (M = Y, Nd, Ce) gives well-defined, bowl-shaped telluroxane clusters. Each of the two half-spheres of the compositions [(PhTe)₁₈{ML}O₂₄]^7+/8+ ({ML} = {Y(NO₃)(H₂O)}²⁺ (1), {Nd(NO₃)(H₂O)²⁺} (2), or {Ce(NO₃)₂}⁺ (3)) are connected by two (compound 3) or four (compounds 1 and 2) PhSeO₂^- bridges. The resulting chalcogenoxane spheres have internal volumes of approximately 1500 ų. Charge compensation is provided by nitrate ions and/or [Na₂(NO₃)₈]^6- clus
