Magneto-structural correlation of three nitronyl nitroxide derivatives carrying imidazol-2-yl, benzimidazol-2-yl, and naphth [2, 3-d] imidazol-2-yl rings as hydrogen-bonding sites is described. In these crystals, an intermolecular hydrogen bond has a role in crystal scaffolding, and the occurrence of magnetic interaction is explained by the contact of ONCNO moieties between the neighboring molecules. In particular, we found that the T-shaped contact of ONCNO moieties is very important for the occurrence of intermolecular ferromagnetic interaction.
