Capturing nonclassical C with double heptagons in low-pressure combustion

A double-heptagon-containing C 70 H 6 (dihept-C 70 H 6 ) was isolated and unambiguously characterized in the soot of low-pressure combustion, which shares the identical heptagonal cage as dihept-C 70 Cl 6 previously identified in the products of carbon arc, and thus represents the first nonclassical...

Summary:A double-heptagon-containing C 70 H 6 (dihept-C 70 H 6 ) was isolated and unambiguously characterized in the soot of low-pressure combustion, which shares the identical heptagonal cage as dihept-C 70 Cl 6 previously identified in the products of carbon arc, and thus represents the first nonclassical fullerene isolable in both carbon arc and combustion. A novel nonclassical fullerene dihept-C 70 H 6 , captured from low-pressure combustion, is considered to be vital evidence for the further study of heptafullerenes.
