On the formation of smaller p-block endohedral fullerenes: bonding analysis in the e@c 20 (e5si, ge, sn, pb) series from relativistic dft calculations

Abstract

Experimentally characterized endohedral metallofullerenes are of current interest in expanding the range of viable fullerenic structures and their applications. Smaller metallofullerenes, such as M@C-28, show that several d- and f-block elements can be e
