这种相似性得到了最近的工作的支持,许多新的化合物与小分子如H2,NH3,C2H4在温和的条件下反应,在催化领域应用方面表现出一定的潜力。 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...
What Are Transition Metals? Transition metals are the elements of the 10 columns in groups 3 through 12. They can be found at the center of the periodic table, in the shorter columns between the eight tall columns of the main group elements. Transition Metals: Definition For an element to ...

All aspects of the investigations of metal-metal multiple bonds also apply to a particular class of compound that has, however, enjoyed little lime-light and thus deserves the present review: complexes with multiple bonds between transition metals and substituent-free (bare) main group elements. ...
