Abstract

We have investigated the alkali metal fulleride Na2CsC60 by23Na nuclear magnetic resonance (NMR), The NMR line of the tetrahedral site is split below 170 K (T and T′ lines) similarly to the A3C60 compounds with A=Rb or K. The intensity fraction of the T′ line follows the same temperature dependence as the13C NMR line width. We have also found that the spectrum is independent of the cooling rate. Spin-echo double resonance measurements show that T and T′ sites are mingled on a microscopic scale. We propose that the different23Na NMR lines correspond to different fullerene orientational environments of the tetrahedral alkaline site.
