Below is a table of where I've found various atoms described as being contained within fullerene-type molecules. Atoms shown are experimentally determined to be endohedral to the particular fullerene molecule. If you know of other ones, please email me them, with a reference to where you have seen them in the literature. Literature references are color coded at the bottom, and refer to the first place I've seen them, with preference to articles referring to multiple atoms (reviews, and not necessarily the synthesis/purification papers). At least it will give you an idea of what is out there, and an entry into the literature.
