Expanded fullerides and electron localisation -- lithium-rich ammoniated C(60) phases.

The synthesis and characterisation of alkali metal fullerides with complex counterions consisting of ammonia ligands coordinated to lithium cations is discussed. The body-centred cubic packing and accompanying low density of fulleride anions produces localisation of the t(1u) outer electrons of the fulleride anions. This is demonstrated by the electronic… CONTINUE READING
