摘要:

The variation of the number and position of OH substituents at the phenyl ring of α-phenyl nitronyl nitroxide radicals yields different H-bonded molecular self-assemblies in the solid state but do not change essentially their molecular spin density distributions. In accordance with the distinct structural dimensionalities, the obtained radicals show a large variety of magnetic behaviors, being the monoorthosubstituted isomer the most remarkable one since it shows a 3-D network of weak H-bonds exhibiting abulk ferromagnetictransition below 0.45K.
