Solid-phase synthesis of europium and terbium complexes with nitrogen-containing heterocyclic compounds under mechanical activation

The interaction of europium(III) and terbium(III) nitrates with nitrogen-co ntaining heterocyclic compounds under mechanical activation was shown to le ad to the formation of compounds with the Ln(NO3)(3) . 2D composition, wher e Ln is Eu or Tb; D is 2,2-dipyridyl, 1,10-phenanthroline, or 1,3-diphenylg uanidine. The influence of mechanical activation conditions and additives o n the course of synthesis and the product yield was studied. The compounds were characterized by the methods of chemical elemental analysis and IR and luminescence spectroscopy.
