A molecular 623 link (a six crossing, doubly interlocked, [2]catenane with twisted rings) and a 3<sub>1</sub> #3<sub>1</sub> granny knot (a composite knot made up of two trefoil tangles of the same handedness) were constructed by ring-closing olefin metathesis of an iron(II)-coordinated 2×2 interwoven grid. The connections were directed by pendant phenyl groups to be between proximal ligand ends on the same faces of the grid. The 623 link was separated from the topoisomeric granny knot by recycl ...[more]
