Examples:
Example 1
9'''H,10'''H-9,10-[1,2]Benzenoanthraceno[2''',3''':1,9;6''',7''':1',9';14''',15''':1",9"]tri(C60-Ih)[5,6]fullerene
[three (C60-Ih)[5,6]fullerenes joined by the bridged fused ring system 9,10-[1,2]benzenoanthracene]
Example 2
(C60-Ih)[5,6]Fullereno[9''' ',1''' ':4",5";15''' ',3''' ':4''',5''']difurano[2",3":1,9;2''',3''':1',9']di(C60-Ih)[5,6]fullerene)
[three (C60-Ih)[5,6]fullerenes connected by two furan rings; a fusion name based on the terminal fullerenes]
or
Bis[(C60-Ih)[5,6]fullereno[1',9':4,5]furano][2',3':1,9;2",3":3,15](C60-Ih)[5,6]fullerene
[three (C60-Ih)[5,6]fullerenes connected by two furan rings; a fusion name based on the central fullerene]
Example 3This tricomponent fullerene structure cannot be named by fusion principles. Nevertheless, there are three potential ways to name it.
1. Combine a fusion name for three (C60-Ih)[5,6]fullerenes joined by two fused cyclobutane rings plus the structure modifying prefix 'cyclo':
3,3':15,15'-Bis(cyclo)(C60-Ih)[5,6]fullereno[9''' ',1''' ':3",4";15''' ',3''' ':3''',4''']-
dicyclobuta[1",2":1,9;1''',2''':1',9']di(C60-Ih)[5,6]fullerene
[three (C60-Ih)[5,6]fullerenes connected by two cyclobutane rings; a fusion name based on terminal fullerenes plus two additional single bonds denoted by the structure-modifying prefix 'cyclo']
2. Cite one fullerene as a bridge between the other two fullerenes fused together by a cyclobutane ring.
3,3',15,15'-([1,3,9,15]Epi(C60-Ih)[5,6]fullereno)cyclobuta[1",2":1,9;4",3":1',9']di(C60-Ih)[5,6]fullerene
[the bridging fullerene utilizes primed numbering, in this case double primes]
3. Adapt phane nomenclature (ref. 12) as follows:
1,2,3(1,9,3,15)-Tri(C60-Ih)[5,6]fullerenatetracyclo[1.0.0.01,2.02,3]triphane
Example 4There are three ways to name this multicomponent fullerene consisting of four fullerenes interconnected by three cyclobutane rings.
1. Fused ring nomenclature.
Bis[(C60-Ih)[5,6]fullereno[1',9':3,4]cyclobuta][1''',2''':52,60;1'''',2'''':52'.60']cyclobuta-
[1",2":1,9;3",4":1',9']di(C60-Ih)[5,6]fullerene
[two (C60-Ih)[5,6]fullerenocyclobuta components fused to a cyclobutadi(C60-Ih)[5,6]fullerene]
2. Ring assembly nomenclature plus 'cyclo'.
9,9':9",60':9''',60"-Tris(cyclo)-1,1':52',1":52",1'''-quater(C60-Ih)[5,6]fullerene
[a ring assembly name between four (C60-Ih)[5,6]fullerenes plus three additional single bonds denoted by the structure-modifying prefix 'cyclo']
3. An adaptation of phane nomenclature (ref. 12).
1,4(1,9),2,3(1,9,52,60)-Tetra(C60-Ih)[5,6]fullerenadispiro[1.0.13.02]tetraphane
Note: The spiro recommendations (ref 11) would not use superscript locants in the von Baeyer descriptor for a dispiro system. In this example these numbers are shown to clarify the unusual nature of the dispirotetraphane system.
