Nomenclature for the C 60 - I h and C 70 - D 5h(6) fullerenes (IUPAC Recommendations 2002)

摘要: Fullerenes are a new allotrope of carbon characterized by closed-cage structure consisting an even number three-coordinate atoms devoid hydrogen atoms. This class was originally limited to structures with 12 isolated five-membered rings, the rest being six-membered rings. Although it recognized that existing organic ring nomenclature could be used for these structures, resulting names would extremely unwieldy and inconvient use. At same time also established principles used, or adapted, provide consistent this unique compounds based on name fullerene. However, necessary develop entirely method uniquely numbering systems. paper describes IUPAC recommendations naming two most common fullerenes pentagons, icosahedral C 6 0 fullerene D 5 h -C 7 It adapting nonclosed-cage heterofullerenes, derivatives formed substitution hydrofullerenes, fusion rings systems cage. Finally, suggests methods describing more units denoting configurations chiral their derivatives.
