    • Benzoic acid catalyzes the exchange of amidinium protons thereby rendering them observable by circumventing inhomogeneous line broadening. The association of benzoic acid to benzamidinium is negligible (B. Kratochvíl, J. Ondrácek, J. Hasek, L. Csordás, Collect. Czech. Chem. Commun. 1988, 53, 3131).

    • Given the weakness of the magnetic couplings observed and the relatively long connection paths we invoke in these systems, we cannot rule out the possibility that simple through-space interactions could play a role in magnetic coupling. However, having carefully inspected the structures and packing diagrams for obvious π stacking or other close approaches, we have not found contacts more promising than these hydrogen-bonding pathways as explanations for the difference in magnetic behaviors seen between 2 and 3. Indeed, the shortest through-space coupling distance between nitroxyl spins in paramagnetic material 3 is 6.71 Å whereas the corresponding shortest distance in the coupled antiferromagnetic system 2 is 7.28 Å. These results strongly point toward a through-bond pathway. We thus prefer the interpretation of the hydrogen bond networks because of their self-consistency with the structural chemistry.
