Researchers created a novel spherical supermolecule by encapsulating ortho-carborane within a fullerene-like system. This carbon-free C80 analogue exhibits icosahedral symmetry, marking a significant advancement in supramolecular chemistry.
Area of Science:
- Supramolecular Chemistry
- Inorganic Chemistry
- Materials Science
Background:
- Fullerene-like systems offer unique structural properties.
- Ortho-carborane serves as a versatile inorganic building block.
- Template-controlled aggregation is a key strategy in constructing complex molecules.
Purpose of the Study:
- To synthesize a novel spherical supermolecule.
- To create a carbon-free analogue of C80 fullerene.
- To investigate the formation of icosahedral structures through self-assembly.
Main Methods:
- Template-controlled aggregation of pentaphosphaferrocene and Cu(I)Cl.
- Encapsulation of ortho-carborane within the fullerene-like system.
- Characterization of the resulting spherical supermolecule.
Main Results:
- Successful formation of the spherical supermolecule C(2)B(10)H(12)[{Cp*Fe(eta(5)-P(5))}(12)(CuCl)(20)].
- Demonstration of a carbon-free C80 analogue with icosahedral symmetry.
- Observation of template-controlled aggregation leading to a precise supramolecular structure.
Conclusions:
- The study presents the first example of a carbon-free C80 analogue.
- The synthesized supermolecule possesses icosahedral symmetry.
- This work highlights the potential of fullerene-like building blocks for creating complex inorganic structures.

The chair form is the most stable and derives its name from its resemblance to the “easy chair.” In the chair conformation, two carbon atoms are arranged out-of-plane — one above and one below, minimizing the torsional strain. In the chair form, the bond angle is very close to the ideal tetrahedral value,...
