A spin quintet : The electronic and molecular structure of the metacyclophane‐based spin‐quintet tetraradical 1 with a sterically controlled rigid structure and small fine‐structure parameters is characterized. Pulse‐ESR based 2D electron spin nutation spectroscopy allows the spin multiplicity of 1 to be unequivocally identified, providing its fine‐structure parameters and g ‐values.
