Monoatomic zerovalent main-group element complexes emerged very recently and attracted increasing attention of both theoretical and experimental chemists. In particular, zerovalent silicon complexes and their congeners (metallylones) stabilized by neutral Lewis donors are of significant importance not only because of their intriguing electronic structure but also because they can serve as useful building blocks for novel chemical species. Featuring four valence electrons as two lone pairs at the central atoms, such complexes may form donor–acceptor adducts with Lewis acids. More interestingly, with the central atoms in the oxidation state of zero, they could pave a way to new classes of compounds and functional groups that are otherwise difficult to realize.

主族化学的一个新领域：零价单原子硅化合物及其类似物

单原子零价主族元素络合物是最近才出现的，并引起了理论和实验化学家越来越多的关注。特别是，中性的路易斯给体稳定的零价硅配合物及其同类物（金属酮）不仅具有重要的电子结构，而且还可以作为新型化学物种的有用组成部分，因此具有重要的意义。这样的络合物在中心原子处具有四个价电子作为两个孤对，可以与路易斯酸形成供体-受体加合物。更有趣的是，由于中心原子的氧化态为零，它们可以为否则很难实现的新型化合物和官能团铺平道路。
