In a molecule, each vertex represents a carbon atom that binds to three adjacent carbon atoms. The angle 108 ° of each regular pentagon is close to the ideal angle of the compound 109.5 ° for the sp3 hybridized atom. Each carbon atom is also bonded to a hydrogen atom. The molecule, like fullerene, has Ih symmetry, as evidenced by its proton-NMR spectrum, in which all hydrogen atoms appear at a single chemical shift of 3.38 ppm. Dodecahedran is one of the platonic hydrocarbons along with the cuban and tetrahedran , and is not found in nature.
