Fullerene and Sulfur Compounds

Abstract

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.
