本文综述了高核度过渡金属羰基簇合物的合成和反应化学，并介绍了“合理”合成含1 nm以上金属核的羰基簇合物的新合成策略。固体
本文讨论了锇/汞、锇/金和钌/铜三种金属簇合物的状态结构，讨论了它们的形成、成键和氧化还原性质。提出了如何调整合成策略以制备双氢呋喃的建议
工业上有用的金属化合物簇。最近的工作表明，从簇制备的纳米粒子是催化活性时，锚定内介孔二氧化硅进行了讨论。
The synthesis and reaction chemistry of high nuclearity transilion metal carbonyl clusters is briefly reviewed, and new synthetic strategies leading to the “rational” synthesis of bimetallic clusters containing metal cores of over 1 nm in dimension are described. The solid
state structures of a number of osmium/mercury, osmium/gold and ruthenium/copper bimetallic clusters are discussed with regard to the nature of their formation, and of their bonding and redox properties. Suggestions are made as to how the synthetic strategies can be adapted to prepare bimetallic
clusters of industrially useful combinations of metals. Recent work showing that bimetallic nanoparticles prepared from clusters are catalytically active when anchored inside mesoporous silica is also discussed.
