Abstract

The formation of cationic astatine /I/-coordination compounds with selenium-containing neutral ligands is described. The detection of compound formation and first physico-chemical data on the characterization of this new group of At/I/-compounds were obtained by investigation of their electromigration behaviour in free electrolytes. Se-donors coordinate more strongly to At/I/ than ligands containing carbamide and thiocarbamide. This fact is proved by electromigrational studies on the exchange of N,N′-ethyleneselenocarbamide, respectively N,N′-ethylenethiocarbamide with iodide.
