Fullerene and sulfur compounds

A new method to synthesize fullerene and sulfur compounds, C₆₀S₁₆ and C₇₀S₁₆ compounds of about 1 mm length, has been developed. The C₆₀S₁₆ crystal is a C-centered monoclinic structure of a = 2.0874(1)nm, b = 2.1139(1)nm, c = 1.05690(6)nm and β = 111.9 degree. The C₇₀S₁₆ compound has a primitive monoclinic structure of a = 1.5271(2) nm, b = 1.49971(7) nm, c = 2.18024(9) nm and β = 109.791(1)degree. The crystalline structure of these compounds is constructed by fullerene and S₈-rings. A very small amount of charge-transfer between fullerenes and sulfur rings are expected by first-principle calculation.
