Re: C60 orthorhombic structure

2021-09-24 Thread Alan Hewat 
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 access to ICSD :-) The old neutron powder work I previously referred
to from memory was
Nature (1991) 353, 147-149  *Crystal
structure and bonding of ordered C60*
David, W.I.F.;Ibberson, R.M.;Matthewman, J.C.;Prassides, K.;Dennis,
T.J.S.;Hare, J.P.;Kroto, H.W.;Taylor, R.;Walton, D.R.M.
This paper is copyright by Nature, but have put ICSD details on
https://neutronoptics.com/downloads/C60-icsd_66729.jpg

Below the 249K transition, the structure becomes ordered with a different
cubic phase. You will find more ISIS work on C60 with inclusion compounds,
eespecially superconducting K3C60 on
https://neutronoptics.com/downloads/K-C60-icsd.jpg including Peter
Steven's paper.
Kind Regards, Alan.

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

There are quite a number of papers on C60 superconductors, in particular by
Bill David and colleagues at ISIS, and it would be worthwhile doing a
broader search of the literature.

Kind regards, Alan.

Re: C60 orthorhombic structure

2021-09-24 Thread francois Goutenoire 

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.

Best wishes françois Goutenoire
