19. 1H NMR spectrum at - 50 °C shows a single. broad signal at δ = 1.738, which sharpens and shifts to high field upon raising the temperature to 10 °C (δ = 1.672); it can be attributed to a hexamer. An additional signal for a monomer species is observed first as a shoulder (δ = 1.803, - 30 °C) and then as a sharp signal (δ = 1.741, 10 °C). From both spectroscopic studies the formation of a tetrameric cluster instead of a hexameric one cannot be ruled out.
