Abstract

New C70 fullerides with compositions of MgxC70 at 1 < x ≤ 5 were prepared by solid state reaction. While most samples with 1 < x < 4 were multiphase, a single phase was obtained at x = 5. Mg5C70 was found to be a Mg-saturated phase and its x-ray diffraction profile was successfully assigned to a simple orthorhombic structure with a = 1.684, b = 1.462, and c = 1.384 nm. Mg5C70 was found to be non-metallic and exhibited an anomaly in magnetic susceptibility at approximately 80 K. No superconducting transition was found for MgxC70 (1 < x ≤ 5) down to a temperature of 2 K.
