• We describe herein the self-assembly synthesis of an octanuclear Co [2]catenane {[Co (H L) ] } formed by the mechanical interlocking of two {[Co (H L) ] } rectangles of unprecedented topology. Subtle manipulation of the synthetic conditions allows the isolation of a mixed-valence [Co /Co ] non-catenated rectangle. The Co 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.
