Thanks for this interesting and informative reference! I'm traveling, so only a good time to read but not so much to reply.
My current favorite reference for this: Yuh Fukai's The Metal Hydrogen System, 2nd Edition, Springer, Berlin, 2005. See tables on page 16 and p. 38. The aggregated data presented portray surprises, for me at least.
