One-dimensional (ID) magnetic systems have been extensively studied over the last few decades because they are more chemically tractable between zero-dimensional systems and two- or three-dimensional frameworks. A successful metal-radical approach, has shown great power to construct 1D molecular magnets based on the strong exchange interactions transmitted by radicals. However, the synthesis of radicals and radical-bridged complexes are very challenging due to the active p electron of the radical. Nitronyl nitroxide radicals have been proved to be an extremely versatile family of bridging ligands, which are capable of forming 1D magnetic species with different transition-metal and rare-earth ions to exhibit unique features of AF and FO exchange interactions, long-range magnetic ordering, or magnetization dynamics. Factors that influence the nature of exchange interaction along the chain direction are complicated but play an important role to govern the magnetic properties. In this review, we will provide an overview focus on 1D metal-nitronyl nitroxide complexes, highlighting their structures and magnetic properties. Particular attention is paid to the relation between different types of radical ligands and how to tune the magnetic properties of those magnetic families. (C) 2018 Elsevier B.V. All rights reserved.
