The crystal structure of a new phase of the pnitrophenyl nitronyl &oxide radical compound is described. A study of its magnetic properties reveals the largest intermolecular ferromagnetic coupling reported so far among a series of polymorphs of this compound.
An a-nitronyl nitroxide cation radical, 2-( 3-N-methylpyridinium)-4,4,5,5-tetramethyl-4,5-dihydro-lH-imidazol-l-oxyl 3-Noxide, has been found to possess a unique structure and magnetic properties: the molecules are manifested as dimers with a very short intermolecular contact between the NO group an
