A fulleride Sm6C60 has been synthesized using the high-temperature solid-state reaction. The Rietveld refinement on high-resolution synchrotron x-ray powder-diffraction data shows that Sm6C60 is isostructural with body-centered-cubic A6C60(A=K, Ba). The Raman spectrum of Sm6C60 is similar to that of Ba6C60, and the frequencies of two Ag modes in Sm6C60 are nearly the same as that of Ba6C60, suggesting that Sm is divalent and hybridization between C60 molecules and the Sm atom could exist in Sm6C60. Resistivity measurement shows a weak T-linear behavior above 180 K; the transport at low temperature is mainly dominated by granular-metal theory.
