金属原子簇概念的创始人——F·Acotton从大量事实出发,将金属原子簇化合物分为高价和低价两类,并进行了比较。本文就配位基的选择、金属的选择、M—M键长的比较、高—低价原子簇化合物难于相互转化以及d、S和p轨道在M—M成键中的作用作一论述。 F Acotton, the founder of the concept of metal clusters, proceeded from a large number of facts and classified the metal clusters into two types: high price and low price, and compared them. In this paper, we discuss the choice of coordination sites, the choice of metals, the comparison of M-M bond lengths, the difficulty of transformation of high and low-valent cluster compounds into each other, and the role of d, S and p orbitals in M-M bonding.
