Spiraling into control: A finite linear arrangement of four magnetically coupled copper(II) centers has been generated within a triple-stranded helical motif that was formed through a strict self-assembly process between a single octadentate ligand and CuII ions (see picture). This approach opens the way to constructing finite one-dimensional magnetic chains in a controlled manner.
