We describe herein the self-assembly synthesis of an octanuclear CoII [2]catenane {[Co4(H2L)6]216+} formed by the mechanical interlocking of two {[Co4(H2L)6]8+} rectangles of unprecedented topology. Subtle manipulation of the synthetic conditions allows the isolation of a mixed-valence [Co2III/Co2II]10+ non-catenated rectangle. The CoII centers in the [2]catenane exhibit slow relaxation of their magnetic moment, i. e. single-molecule magnet properties, dominated by quantum tunneling and Raman relaxation processes. This work shows that metallo-supramolecular chemistry can precisely control the organization of single-molecule magnets in topologically complex arrangements.< Leer menos
