Abstract

The preparation of [N(CH3)(4)] C-60. 1.5thf and characterisation of its electronic properties, using susceptibility, EPR and C-13 MAS NMR measurements, is reported. X-Ray powder diffraction shows a simple hexagonal stacking sequence of close-packed C-60 layers, with cations and solvent molecules located in the trigonal-prismatic sites. The electronic properties are consistent with narrow-band metallic behaviour at high temperature. A transition insusceptibility and EPR measurements is seen between 200 and 230 K. A similar synthesis affords a C-60(2-) compound with the same simple hexagonal fulleride packing.
