Since pyrolytic graphite works so well due to delocalized electrons, I would guess that aromatic compounds with one or several benzene rings could be the way to go.
Bithmuth has a fairly low melting point, and possibly (not sure) it remains stronly diamagnetic, but you are looking at room temperature, right?

Bismuth loses most of its diamagnetism on melting. I'm not sure about this but I have a feeling that some sulphides and phosphines are quite diamagnetic. (they are also stinky, toxic and, in some cases, spontanously flammable.)

Joe and Bored:
I'm not a chemist, so I'm just thinking outloud on this post.... Thought experiment: If bismuth powder were applied to an object, say a piece of paper or plastic via some type of adhesive/glue... do you think it would tend to make the object behave as if it were diamagnetic? CM

If bismuth loses its diamagnetic properties on melting, wouldn't polycyclic hydrocarbons do the same as compared to pyrolytic graphite? Remember it is only diamagnetic on the one plane. I wouldn't even mess with phosphine for something like this, yikes, strongly pyrophoric, highly toxic, and difficult to liquefy (maybe if this was all in a sealed aparattus or something).
Would a suspension of bismuth or other solid particles work? Since water and phosphine and other polar molecules are diamagnetic, what about anhydrous ammonia or just strong ammonia solution? Maybe stibine since it is the only ammonia analogue I know of for sure with reasonable vapor pressure at room temp. That's getting rather exotic however. Anyone know if the ammonia analogue of bismuth (BiH3) is stable or exists?

What happens if a large strong magnetnetic feild is applied to bistmouth while it cools slowly? Do you get a nice sculputure with large spikely curved crystals?
