Fu-8. Bridged Fullerenes

Bridges between rings fused to a fullerene and a parent fullerene or between two different rings fused to the same fullerene are named using established bridge prefix names. In the latter case, citation of bridge components and numbering begins with the bridge atom adjacent to the fused component with the least primed numbers (the lower number) and continues with the next primed number following the highest primed number of the fused component.

Examples:

1,4-Ethano(C₇₀-D_5h(6))[5,6]fullerene

1,4-[1,2]Benzeno(C₇₀-D_5h(6))[5,6]fullerene

Note: The CA index name is 1,4[1',2']-benzeno[5,6]fullerene-C₇₀-D_5h(6).

72,73-Dihydro-71H-1,4-epicyclopropa(C₇₀-D_5h(6))[5,6]fullerene

Note: The uninverted CA index name is 72,73-dihydro-71H-1,4-endo-cyclopropa[5,6]fullerene-C₇₀-D_5h(6).

1,4-[3,4]Furano(C₇₀-D_5h(6))[5,6]fullerene-72,74-dione

Note: The CA index name is 1,4[3',4']-furano[5,6]fullerene-C₇₀-D_5h(6).

2,5-(Silanomethanosilano)(C₇₀-D_5h(6))[5,6]fullerene

1a,3a-Propano-1a,3a-diaza-1(2)a,3(4)a-dihomo(C₆₀-I_h)[5,6]fullerene

Note: The CA index name is 3a,5a-propano-3a,5a-diaza-1,5(5a):2,3(3a)-dihomo[5,6]fullerene-C₆₀-I_h.

7,20:8,10:11,13:14,16,17:19-Pentaetheno-1,2,3,4,5,6,9,12,15,18-decanor(C₆₀-I_h)[5,6]fullerene

Note: Double bonds are shown here for illustrative purposes only. Double bonds are not normally shown in fullerene, fulleroid, or fullerene component structures in these recommendations.

11,13:14,16:17,19-Trietheno-3',10:6',20-dimethenobenzo[7,8]-1,2,3,4,5,6,9,12,15,18-decanor(C₆₀-I_h)[5,6]fullerene

Note 1: Double bonds are shown here for illustrative purposes only. Double bonds are not normally shown in fullerene, fulleroid, or fullerene component structures in these recommendations.

Note 2: The current CA index name is 6,7(7a):8,9(9a):11,12(12a):14,15(15a):17,18(18a)-pentahomo-1,2,3-trinor[5,6]fullerene-C₆₀-I_h

3'-Methoxy-6H-4',5-epoxybicyclo[3.2.2]nona[2,8]dieno[6',7':1,9](C₆₀-I_h)[5,6]fullerene

3'H,3"H-3',3"-(Methanooxymethano[1,4]benzenomethanooxymethano)dicyclopropa[1,9:32,33](C₆₀-I_h)[5,6]fullerene
