Luminescence and aggregation studies of hexanuclear platinum–copper acetylide complexes. Crystal structure of the luminescent metal–metal bonded dimer [Pt₂Cu₄(C[triple bond, length half m-dash]CPh)₈]₂

Abstract

The luminescent metal–metal bonded dimer of a known hexanuclear platinum–copper acetylide complex has been synthesized and characterized by X-ray crystallography; the complex is shown to exist in the dimeric form only in concentrated solution through a Pt–Pt bonding interaction.
