Hi,
I'm looking for crystal structure of solid methane in its phase I.
Some papers indicate that is has Fm3m symmetry, but nothing more.
I search in materials project, but nothing.
Anybody ?
Thanks!!
Dear Christian Helman ,
in addition to the paper mentioned by Frank T. Edelmann please see: Article A Microscpoic Model for the Neutron Dynamic Structure Factor...
Although also here the paper title does not deal with solid methane of phase I, it is stated at the beginning of the section II:
" In phase I, methane has a face-centered cubic (fcc) structure with four orientationally disordered molecules per unit cell". This statement is also found at the introduction part of Frank's paper given above.

Alternatively you may ask one of the authors ( e.g. R. M. Ibberson
) of the paper which Frank mentioned.That paper is also avilable here on RG:

Hello,
my laboratory group has investigated the structure of solid methane.
In the works that I will attach below, you can see the data of structural studies of solid methane in disordered and ordered phases.
