Numbering of Fullerenes (IUPAC Recommendations 2004)

3.1.5.

Systematic numbering for other fullerenes having at least one symmetry axis (Cn, n>1) and a contiguous helical numbering pathway determined on the basis of rules Fu-3.1.1 to Fu-3.1.4.

3.1.5. Systematic numbering for other fullerenes having at least one symmetry axis (Cn, n>1) and a contiguous helical numbering pathway determined on the basis of rules Fu-3.1.1 to Fu-3.1.4.

Fullerenes of this class do exist for which the application of Fu-3.1.1 to Fu-3.1.3 does not allow to distinguish among several contiguous helical numbering pathways. To solve this problem the additional rule Fu-3.1.4 has been adopted. The use of this new rule leads to numberings that in some cases are different from those obtained by CAS [ref 3]. Examples of fullerenes whose numbering requires application of Fu-3.1.4 are described below.
