On octahedral fulleroids

Reaction of diazocompounds with C70: unprecedented synthesis and characterization of isomeric [5,6]-fulleroids.

The synthesis of a variety of PCBM-type [5,6]-fulleroids and their further highly selective photoisomerization to the respective [6,6]-methanofullerenes is presented. Interestingly, the chemical reactivity of [5,6]-fulleroids reveals the same trend (a > b > c > d) to that observed for pristine C70 (α > β > γ > δ).

Fantasmagoric Fulleroids Revisited

New strange fulleroids are built up by using the three classical composite map operations: tripling (leapfrog Le), quadrupling (chamfering Q) and septupling (capra Ca) on the starting structure dodecahedron. These transforms belong to the icosahedral symmetry group and show interesting mathematical and (possible) physico-chemical properties. Topological symmetry data of the presented cages are ...

Synthesis of Single-Crystalline Octahedral Co3O4 with Solid-State Thermal Decomposition

In this paper, single crystalline octahedral Co3O4 with dimensions about 100–500 nm and smooth surface has been prepared by solid-state thermal decomposition of cobalt(II) Schiff base complex Co((3,4-MeO-ba)2 en)Cl2 as new precursor at 450ºC under air atmosphere for 3.5 h. Surface morphology of the products were characterized by Fourier transform infrared spectroscopy (FT-IR), X-ray powder ...

Enumeration of Conformers of Octahedral [M(ABC)_{6}] Complex on the Basis of Computational Group Theory

Conformers of [M(ABC)6] complex have been enumerated on the basis of computational group theory, where M is the central metal, and ABC is the ligand, bound to M through A. Based on the 16 conformers of the M(AB)6 core unit, 7173 conformers have been found for the [M(ABC)6] complex, which are assigned to nine point groups, 1 D3d, 4 D3, 4 S6, 5 C2h, 7 C3, 182 C2, 15 Cs, 23 Ci, and 6932 C1.
