虽然绝大多数无机化学涉及主族原子向金属的电子给予，但存在一个耐人寻味但又相反的一面：刘易斯-碱性金属向刘易斯-酸性主族原子(最常见的是硼)提供电子密度。这些所谓的“Z型”配体，以及其他不那么清晰的络合物，都是这种金属-配体角色颠倒的例子。这篇透视性的文章介绍了金属与硼的配位键合，并试图将这些配合物的光谱数据和结构数据联系起来。
While the vast majority of inorganic chemistry involves electron donation from main-group atoms to metals, an intriguing yet flip-side exists: where Lewis-basic metals donate electron density to Lewis-acidic main-group atoms (most often boron). These so-called "Z-type" ligands, along with other less clear-cut complexes, are examples of this metal-ligand role reversal. This perspective article offers an introduction to metal-to-boron dative bonding, and attempts to correlate spectroscopic and structural data from the complexes.
