Abstract

Magnesium fullerides Mg_xC₆₀ (1<x≤6) were prepared by a solid-state reaction. Mg_3.9C₆₀ was assigned a rhombohedral structure with a=0.999 nm, α=55.1°. All Mg _xC₆₀ fullerides were found to have almost the same rhombohedral structure. Mg_4.9C₆₀ did not show metallicity based on the electrical resistivity and electron spin resonance measurements. Mg_xC₆₀ appears to form polymers over a wide range of Mg concentrations and behaves as a non-magnetic insulator.
