Co–Co and Co–Fe cyano-bridged pentanuclear clusters based on a methylpyrazinyl-diamine tetradentate ligand: spin crossover and metal substitution effects†
Abstract
A pentanuclear CoII–CoIII cluster complex has been developed by a solvothermal synthesis. Its highly stable metal-mixed iron–cobalt derivatives display robust spin crossover (T1/2 = 268 K) controlled by the degree of substitution.
