Dear Francois.
I did a quick non-exhaustive search of ICSD for pure C60, and posted the
results on https://neutronoptics.com/downloads/C60-icsd.jpg
This includes claims of tetragonal and orthorhombic structures. You can
search Google with the paper titles to find the references if you don't
have
Dear Rietveld users,
We are currently looking for the atomic structure (cif file) of the C60
Orthorhombic cell
The previous paper : "Structure and superconductivity of single
crystalline C60" from Koichi Kikuchi et al.
Physica C in 1975
The cell parameters are given a=25.011 Ang,
Dear Francois.
Thank you for putting the paper on your private server rather than sending
it to the whole list. However the correct link should be:
https://perso.univ-lemans.fr/~fgouten/C60/
Koichi KIKUCHI, et al Physiea C 185-189 (1991) 415-416
STRUCTURE AND SUPERCONDUCTIVITY OF SINGLE
Dear Rietveld users,
Sorry for the mistake, the paper was published in 1991.
I put the paper in the link
http:\\perso.univ-lemans.fr\~fgouten\C60
From the previous answer it seems that it is not really realiable.
