Hydrometal analogues of aromatic hydrocarbons: a new class of cyclic hydrocoppers(I)

J Am Chem Soc. 2003 Feb 5;125(5):1136-7. doi: 10.1021/ja028786j.

Abstract

A new class of cyclic hydrocoppers(I) with the general formula CunHn (n = 3-6), resembling the cyclic hydrocarbon analogues, were predicted by means of DFT calculations to be stable molecules adopting a perfect planar configuration of high-symmetry characteristic of the aromatic systems.
