Three novel solid cryptates of a cage-type N2O6-heteroatom hexabenzocryptan
d (L) with RE(III) (RE =Sc, La) chlorides and lanthanum nitrate respectivel
y have been synthesized and characterized by IR and H-1 NMR spectra, TG-DTA
analyses and molar conductances. The composition of these cryptates has be
en determined as RE2Cl6L.4H(2)O (RE =Sc, La) and La-2 (NO3)(6)L.2H(2)O.
