Tetrahedrane is a platonic hydrocarbon with chemical formula 44 and a tetrahedral structure. Extreme angle strain (carbon bond angles deviate considerably from the tetrahedral bond angle of 109.5°) prevents this molecule from forming outside of man-made production. In 1978, Günther Maier prepared a stable tetrahedrane with four tert-butyl substituents. These substituents are very bulky, and completely envelop the tetrahedrane core. Bonds in the core are prevented from breaking bec… (More on Tetrahedrane)
