Abstract
The synthesis, solution studies, X-ray structures and magnetic properties o f two new radical derived pyrazole ligands, based on alpha -nitronyl and im ino nitroxides are reported. The spin distribution on the radicals has been studied in solution using EPR spectroscopy on dilute solutions. In concent rated solutions the radicals form aggregates in solution in which the magne tic interactions have been studied using low-temperature EPR spectroscopy. (C) 2001 Elsevier Science Ltd.
