Cluster chemistry

Tetrahedrane is a hypothetical platonic hydrocarbon with chemical formula and a tetrahedral structure. The molecule would be subject to considerable angle strain and has not been synthesized . However, a number of derivatives have been prepared. In a more general sense, the term tetrahedranes is used to describe a class of molecules and ions with related structure, e.g. white phosphorus.

In chemistry, a superatom is any cluster of atoms that seem to exhibit some of the properties of elemental atoms. One example of a superatom is the cluster .

The dodecaborate(12) anion, [B12H12]2−, is a boron hydride cluster anion. It forms a variety of colorless salts with alkali metal and quaternary ammonium cations. The cluster has a distinctive icosahedral structure with 12 boron atoms at the vertices, each boron atom is attached to a hydrogen atom. Its symmetry is classified by the molecular point group Ih.
