Molecular formula : MW : CAS :
nature : the surface reflects polyhedron (F), the number of vertices (V) and Prism (E) the relationship between the rules can be expressed as V = F + E +2. Many non-metallic cluster skeleton structure with this rule, such as white phosphorous P4 the tetrahedron skeleton, cubane - C8H8 skeleton and the cube Te6 (AsF6) 4_ s 2SO2 which Te4 + ion 6 triangular prism of skeletons. Fullerenes closed spherical or elliptical structure of the molecule, if the five-ring and six ring is composed of two convex, according to Euler rules, which will contain 12 5 yuan Central, six yuan in Central unlimited number. If it is purely a six-ring component, there would be no closure. Euler and other rules can combine the rules, the metallic structure of the cluster rules.
