Cubane-type cluster

A cubane-type cluster is an arrangement of atoms in a molecular structure that forms a cube.

With chemical formula C8H8, cubane has carbon atoms at the corners of a cube and covalent bonds forming the edges.

The whole cluster is typically anchored by coordination of the iron atoms, usually with cysteine residues.

[2] Several alkyllithium compounds exist as clusters in solution, typically tetramers, with the formula [RLi]4.

Like the carbon-based cubane compounds, octaazacubane is predicted to be highly unstable due to angle strain at the corners, and it also does not enjoy the kinetic stability seen for its organic analogues.
