A new form of pure, solid carbon has been synthesized consisting of a somewhat disordered hexagonal close packing of soccer-ball-shaped C60 molecules. Infrared spectra and X-ray diffraction studies of the molecular packing confirm that the molecules have the anticipated 'fullerene' structure. Mass spectroscopy shows that the C70 molecule is present at levels of a few per cent. The solid-state and molecular properties of C60 and its possible role in interstellar space can now be studied in… Expand
Fullerites: New forms of crystalline carbon
The discovery of the new crystalline forms of carbon, in which fullerenes such as C60 array in a lattice, was the result of work that aimed at a better understanding of interstellar dust. In theseExpand
A new crystalline form of carbon based on the C36 fullerene: Simulating its crystal and electronic structure
A new crystalline allotropic form of carbon consisting of covalently bound fullerenes C36 of symmetry D6h is suggested. The structure of the unit cell of this compound was simulated. The unit-cellExpand
C36, a new carbon solid
Under appropriate non-equilibrium growth conditions, carbon atoms form relatively stable hollow clusters of well-defined mass number, collectively known as fullerenes. The mass production,Expand
Molecular structure of the C70 fullerene
Abstract The molecular structure of C 70 has been studied between 20 and 300 K using high- Q pulsed powder neutron diffraction of solid C 70 . The intra- and inter-molecular pair correlationExpand
Crystalline C60·2CHBr3 solvate: A solid-state study

Polymorphism in Carbons and Parent Materials
It has long been known that solid carbon can be found in various guises: besides the confirmation that the different forms of graphite and diamond are crystalline varieties of this element, new formsExpand
Fullerenes—preparation, properties, and carbon chemistry
Abstract This article reviews the current literature on the new form of carbon based on the fullerene structure. It is now clear that fullerenes can be made from sources other than graphite. ProgressExpand
A non-fullerene form of C60 and layered metal-doped C60 solid
Abstract As a consequence of intermolecular collisions or internal strain, we suggest a “barrel”-type shape of the C 60 molecules instead of a spherical (fullerene) form. The stretched C 60 versionExpand
A Rational Chemical Synthesis of C60
TLDR
The methods developed for the target-specific synthesis of fullerenes, applied here to a synthesis of C60, should make possible the directed laboratory preparation of other fullerene as well, including those not accessible by graphite vaporization. Expand
The fullerenes — new allotropic forms of carbon: molecular and electronic structure, and chemical properties
In the early 1970s Osawa (and also Bochvar and Gal'pern) theoretically discussed the possibility of the existence of polyhedral carbon clusters, and predicted some of their properties. In 1985 it wasExpand

TLDR
The intriguing revelation that 12 pentagonal "defects" convert a planar hexagonal array of any size into a quasi-icosahedral cage explains why some intrinsically planar materials form quasi-crystalline particles, as appears to occur in the case of soot. Expand
