Thanks, I found the paper and looks like it has everything I was looking for. It also has the experimental data for several other phases too which I would have needed at some point as well.Mike H said:No time to figure this out (am in a bit of a rush), but I remembered that this guy out in California did some work on this topic a while back and managed to find the citation via Google which may help:

I would think a face-centered cubic structure would be OK as a first try, though. As I had to explain to one of my students a while back, you see the difference between the strength of weak chemical interactions versus covalent interactions when comparing carbon dioxide (dry ice) and silicon dioxide (quartz) quite clearly....
