✦ Synopsis

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 and the pyridinium ring, and the dimer units form an organic 2D triangular lattice. It includes both ferromagnetic and antiferromagnetic intermolecular interactions.
