Hypercubane

Hypercubane is a hypothetical polycyclic hydrocarbon with the chemical formula C40H24. It is a molecular analog of the four-dimensional hypercube or tesseract. Hypercubane possesses an unconventional geometry of the carbon framework. It has Oh symmetry like classic cubane C8H8. The structure is that of octamethyl cubane—a carbon attached to each corner of cubane itself—having each of those carbon substituents joined to each of its neighbors by an ethylene-1,2-diyl linker to form an outer cage. The edge of each inner core and its outer linker form a cyclohexene.
