延伸金属原子链（EMAC）构成了在组成金属离子的长度和身份两者上不同的分子的多样性组。因此，它们对我们理解金属-金属键合及其与结构、磁性和电子输运性质的关系提出了重要挑战。在这篇综述中，我们总结了我们目前的理解，在这些链中的低对称性扭曲的起源和它们对电流通过分子的影响。我们的结论是，结构，磁化学和电阻都是密切相关的，通过共享的前线轨道的能量和方向的依赖。
The extended metal atoms chains (EMACs) constitute a diverse group of molecules differing in both length and identity of the constituent metal ions. They therefore present important challenges to our understanding of metal–metal bonding and its relationship to structural, magnetic and electron transport properties. In this review we summarise our current understanding of the origins of low-symmetry distortions in these chains and their impact on current flow through the molecule. We conclude that structure, magnetochemistry and resistance are all intimately related through a shared dependence on the energies and orientations of the frontier orbitals.
