One-dimensional (1D) 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.

在过去的几十年中，一维（1D）磁性系统已经得到了广泛的研究，因为它们在零维系统和二维或三维框架之间具有更强的化学易处理性。成功的金属自由基方法显示出强大的能力，可以根据自由基传递的强交换相互作用来构建一维分子磁体。然而，由于自由基的活性p电子，自由基和自由基桥接的配合物的合成非常具有挑战性。硝基氧化氮自由基已被证明是桥联配体的一种极其通用的家族，它们能够形成具有不同过渡金属和稀土离子的一维磁性物种，表现出AF和FO交换相互作用，远距离磁有序性的独特特征，或磁化动力学。影响沿链方向的交换相互作用的性质的因素很复杂，但在控制磁性方面起着重要作用。在这篇综述中，我们将概述一维金属-亚硝酰基一氧化氮配合物，重点介绍其结构和磁性。特别要注意不同类型的自由基配体之间的关系，以及如何调整这些磁性家族的磁性。
