Octahedral hexanuclear clusters such as [Mo6Cl8]4+ and [Re6Q8]2+ (Q = S or Se) are well known for their electrochemical and photoluminescent properties. Over the years, our group has been interested in preparing hexanuclear clusters containing novel ligands and subsequently studying the physical properties and the reactivity of these new cluster complexes. Recently, we reported the preparation of a family of hexanuclear rhenium cluster complexes containing benzonitrile (or para substituted benzonitrile) ligands (Inorganic Chemistry, 2012, 51, 7825). Notably, these compounds, and their tetrazolato analogues, have been found to display luminescent properties. The details of our investigation into the excited state lifetimes and the quantum yields of both series of complexes (nitrile and tetrazolate) will be discussed in this presentation.
