Abstract

An organometallic Au₁₃ cluster having two σ-bonded acetylide ligands was synthesized and its structure was determined by X-ray crystallography. Absorption spectral studies indicated the presence of electronic coupling between the superatomic Au₁₃ core and the acetylide π-orbitals, which was supported by theoretical considerations.
