Can All Pure Compounds Be Crystallized From Solution?

[Welwynformed]

Could you crystallize gold/aluminium/etc. (Or even mixtures of them!) from mercury? Or can M@C60 be crystallized to give an effectively rigid array of 'metallo' atoms? Does gold/copper displace aluminium from mercury?

Curiouser and curiouser. Your last sentence implies that you're seeking advice on a pretty fundamental area of chemistry involving the reactivity series. It's not rocket science and the answer shouldn't be that difficult to see.
On the other hand, endohedral metallofullerenes are a different matter. I suggest you start looking at Gallium doped M@C60 and then cf Lanthanum.
Yes, it is possible to crystallise the said elements from mercury. I'll leave you to work out how.

Gold isn't a compound.

[theprof]

Canary42, no indeed but perhaps the OP is implying that the mercury is contaminated with Gold and/or aluminium compounds.

NO
