14N and 45Sc NMR study of trimetallic nitride cluster (M3N)6+ dynamics inside a icosahedral C80 cage

Abstract

The dynamics of the trimetallic nitride (M(3)N)(6+) (M = Sc, Y and Lu) clusters in the I(h)-(C(80))(6-) cage have been studied by (14)N and (45)Sc nuclear magnetic resonance. These NMR studies suggest that the motional barrier of (M(3)N)(6+) is related to the cluster size and increases in the series (Sc, Y, and Lu).
