Abstract

Hexanuclear silver(I) alkynyl phosphine complexes with anthryl (An) and naphthyl (Np) moieties, [{Ag₃(μ-dppm)₃(μ₃-η¹-CC)}₂An-9,10](BF₄)₄ and [{Ag₃(μ-dppm)₃(μ₃-η¹-CC)}₂Np-1,5](BF₄)₄, have been synthesized. X-Ray crystallography has been used to study the single crystal structure of one of the complexes. This class of silver(I) complexes was found to be emissive at both room and low temperatures in various media, showing green to orange luminescence at ca. 524-593 nm. The electrochemical properties have also been studied by cyclic voltammetry, and an irreversible anodic wave for the alkynyl-centered oxidation was observed. A computational study has been performed to provide further insight into the spectroscopic origin.
