✦ Synopsis

Polymers of silsesquioxane structure, poly [bis-(3-silsesquioxanyl-propylamino)]sulfoxide (IV) and -sulfone (V) have been prepared and examined as complexation agents toward samarium(III) and thulium(III). Polymer IV was an effective complexation agent toward both of these elements. However, polymer V was an effective complexation agent only toward thuliurn(III) ions.

The selective complexation of polymer V with thulium is not affected by the presence of excess amounts of lanthanum, cerium, neodymium, or samarium salt. This suggests that polymer V may prove to be useful in rare-earth element (REE) separation and isolation. The selective complexation of V with thulium(III) is also observed in the presence of nickel(II), copper(II), or lead(lI) salt.

## Abstract From the two nitrogen‐rich ligands BT^2−^ (BT=5,5′‐bitetrazole) and BTT^3−^ (BTT=1,3‐bis(1__H__‐tetrazol‐5‐yl)triazene), a series of novel rare earth metal complexes were synthesised. For the BT ligand, a vast number of these complexes could be structurally characterised by single‐cryst
