摘要：

A series of nitronyl nitroxide derivatives of benzene, bearing halogen atoms at the ortho position, have been prepared and show a remarkable substituent effect of the ortho halogen atoms on their magnetic properties. Among them, the fluorine derivative 1 is found to behave as a ferromagnet with a T-c of around 0.3 K based on ac susceptibility and heat capacity measurements, and its X-ray analysis revealed that the crystals consist of three-dimensional networks of nitroxide radicals bonded through methyl or phenyl groups.
