| Abstract: | The complexes Ru(CN)4(HAT)]2-, {Ru(CN)4}2(mu2-HAT)]4- and {Ru(CN)4}3(mu3-HAT)]6- (HAT = hexaaza-triphenylene) contain four, eight and twelve externally-directed cyanide ligands, respectively; they show strongly solvatochromic and intense MLCT absorptions, and 3]6- forms a high-dimensionality cyanide-bridged coordination network with Nd(III), in which Ru --> Nd energy transfer results in sensitised near-IR luminescence. |
