Chemists have long sought to duplicate the rich chemistry of carbon compounds with the related elements silicon and germanium. In his Perspective, Schleyer discusses work published in the same issue by Sekiguchi et al. (p. 60) in which free cations containing germanium, an elusive target of organic chemists, have been synthesized.
