Cyanide-bridged tetradecanuclear RuII3MII11 clusters (MII=ZnII and CuII) based on the high connectivity building block [Ru3(HAT)(CN)12]6-: structural and photophysical properties.
Reaction of the anionic cyanometallate chromophore [{Ru(CN)4}3(micro3-HAT)]6- with [MII(tren)]2+ complexes (M=ZnII, CuII) provides discrete tetradecanuclear clusters of formula [{MII(tren)(micro-CN)}11{Ru3(HAT)(CN)}]16+; the weak luminescence of the Ru3 chromophore is substantially enhanced in the presence of ZnII ions, whereas it is completely quenched when CuII centers are present.
