Cubane point group

Type 4. More than one axis higher than twofold point groups I d, /, , /, (also Th, T, 0,1). Methane (Td), cubane (Oh, Figure 1.1), dodecahedrane (//, Figure 1.1), and buckminsterfullerene, Cat (E, Chapter 11). The symbol Kh denotes the point group of the sphere. 

Although most molecules in point groups /ft, 0, Ta, C, C and C may be assigned by inspection, some appear unusual. Consider the cubic symmetry of cubane. CBH8. To... 

Cyclooctatetraene from cubane, 203 point group of, 6 Cyclooctatrienone, 289 co-Cyclooctene IP, 102... 

Cubane 112 (pentacyclo[4.2.0 0. 0. ]octane) belongs to point group Oh which has been confirmed by X-ray analyses The 28 occupied molecular orbitals of 111 span the following irreducible representations of the group Oh ... 

Roussin s black salt has a more complex cluster structure. The [Fe4(NO)7S3] displays an incomplete cubane geometry of the anion cluster and consists of a tetrahedron of iron atoms with sulfide ions on three faces of the tetrahedron (see Scheme 3). The point group symmetry of the anion is Csv Three iron atoms... 

Among all the isomers of fullerenes C32 we choice the molecule with cubic point symmetry group Oh. The molecule cage is formed by 12 hexagonal and 6 square faces. The atoms disposed in vertex of squares take part in forming of intermolecular bonds in dimer (C32)2 and cuban-like cluster (C32)s-... 

The Government of the Republic of Cuba also considers that it has the right to require that the entry of any inspection group mandated by the Organization for the Prohibition of Chemical Weapons, to carry out in the territory of Guantanamo Naval Base the verification activities provided for in the Convention, should be effected through a point of entry in Cuban national territory to be determined by the Cuban Government.
