Abstract
A systematic study of the synthesis conditions in correalation with low-tem perature magnetic properties is reported in 1-(3-aminophenyl)-1H-methanoful lerene(C-60)-(Cp2Co) (APhCo) and 1-(3-nitrophenyl)-1H-methanofullerene(C-60 )- (Cp2Co) (NiPhCo), with a Curie temperature of T-c = 15 K; the latter is a newly discovered fullerene ferromagnet. The crystallisation conditions ar e found to play a critical role in determining the low-temperature ferromag netic properties of these fullerene charge-transfer ferromagnets.
