Stacked against the odds: A bridged mixed‐valent compound with direct through‐space interactions between the charge‐bearing units in its singly charged paramagnetic and its doubly charged diamagnetic forms is isolated and characterized by X‐ray crystallography and spectroscopy (see scheme). π‐Stacking interactions for the singlet diradicaldication were more pronounced than for the doublet monocation
