I know caffeine acts somewhat as a weak base. Does anyone know if it has the tendency to complex with weak lewis acids (like Magnesium/Nickel Salts),
as these salts would with ammonia?

i have found it that a solution of magnesium chloride and caffeine somewhat weakens in its psychoactive properties over time
im looking for explanations of this phenomena and so far only idea have been exposure to UV and the magnesium chloride breaking down the caffeine,
could be its chelating, too?

I doubt it's a chelate, but it does form complexes.

This one has a crystal structure for a copper(II) carboxylate caffeine complex. It's dimeric, like copper(II) acetate monohydrate, with the
carboxylate ligands bridging the two coppers, and the caffeine ligands occupying the position that the water ligands would have been. Monodentately.
