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 Å3. Charge compensation is provided by nitrate ions and/or [Na2(NO3)8]6- clusters, which are located inside and surrounding these spheres.

Structural Isomerism
Isomers are different chemical species that have the same chemical formula. Structural isomerism of coordination compounds can be divided into two subcategories, the linkage isomers and coordination-sphere isomers.
Linkage isomers occur when the coordination compound contains a ligand that can bind to the transition metal center through two different atoms. For example, the CN− ligand can bind through the carbon atom or through the nitrogen atom. Similarly, SCN− can...
