70, [30] but fullerenes with 72, 76, 84 and even up to 100 carbon atoms are commonly obtained. The smallest possible fullerene is the dodecahedral C 20. There are no fullerenes with 22 vertices. [31] The number of different fullerenes C 2n grows with increasing n = 12, 13, 14, ..., roughly in proportion to n 9 (sequence A007894 in the OEIS).
The vertices of the 26-fullerene graph can be labeled with sequences of 12 bits, in such a way that distance in the graph equals half of the Hamming distance between these bitvectors. This can also be interpreted as an isometric embedding from the graph into a 12-dimensional taxicab geometry. The 26-fullerene graph is one of only five ...

Fullerenes are sparingly soluble in aromatic solvents and carbon disulfide, but insoluble in water. Solutions of pure C 60 have a deep purple color which leaves a brown residue upon evaporation. The reason for this color change is the relatively narrow energy width of the band of molecular levels responsible for green light absorption by ...
Fullerene purification is the process of obtaining a fullerene compound free of contamination. In fullerene production mixtures of C 60 , C 70 and higher homologues are always formed. Fullerene purification is key to fullerene science and determines fullerene prices and the success of practical applications of fullerenes.
The Laves graph or K 4 crystal is a theoretically predicted three-dimensional crystalline metastable carbon structure in which each carbon atom is bonded to three others, at 120° angles (like graphite), but where the bond planes of adjacent layers lie at an angle of 70.5°, rather than coinciding.
