Transition metalPolysulfido complexMain group and transition metals form complexes with polysulfido ligands of a remarkable structural variety and complexity. These compounds are of high scientific interest but in addition have the potential for serving as catalysts in important industrial processes. The ...
Figure 1 Similarity of H2 interactions with main-group and transition-metal compounds. 上图说的是H2和主族元素以及过渡金属反应的相似性。a中H2的p (HOMO) 和ArMMAr (M=Ge or Sn; Ar’=C6H3-2,6(C6H3-2,6-i-Pr2)2)的n1 (LUMO)前线轨道,这和b中H2与过渡金属M的d轨道反应是可以比较的。 文...
After group 12, elements become less and less like metals as they approach the noble gases in group 18. Transition Elements: Properties Many transition metals have similar properties, due to their similar locations on the table. These properties include: The ability to conduct heat and electricity...
