Here's a pic of the molecule:
I've been investigating this system to test a computational chem method, but I've realized I don't really know a name for this system. $I-pyr_2$? $py_2I$?
In my mind I call it "pip" for pyridine-I-pyridine, but I don't want to publish and look silly finding out this has a common non-systematic name later (ex: quinine, caffeine, etc).
I'm not worried about getting an IUPAC name exactly right, becuase nobody actually does that. But if there's a more common way of calling it, that's what I want.
