A family of heterobimetallic cubes shows spin-crossover behaviour near room temperature A family of heterobimetallic cubes shows spin-crossover behaviour near room temperature

Starting from simple building blocks, six heterobimetallic cubes were obtained, following a straight-forward subcomponent self-assembly strategy. Three iron(II) based cages showed spin-crossover behaviour in solution. The crossover temperature was strongly dependent on interchangeable aldehyde components, giving rise to an efficient toolkit to manipulate magnetic behaviour.
