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). {pi}-Stacking interactions for the singlet diradical dication were more pronounced than for the doublet monocation, despite the Coulomb repulsion effect in the diradical dication.
