The effects of tridentate ligand structure, central atom, co catalyst and supported on property of catalysts are presented.
介绍了三齿配体结构、中心金属原子、 助催化剂、负载化等对催化剂性能的影响；
Focuses on the method to determine the hybrid types of central atom, and Equivalent hybridization, and inequivalent hybridization.
重点介绍了判断中心原子杂化类型的方法，以及杂化的等性与不等性。
In this model the arrangement of bonds around the central atom is considered to depend upon how many valence-shell electron pairs.
在这个模型中，认为围绕中心原子的化学键的排列取决于价层中电子对的数量。
So it's trigonal because we have these three atoms that are bound to the central atom here, and if you picture it, it's actually shaped like a pyramid.
这里三角形是因为,我们有3个原子核中心原子成键，如果你画它，它就是金字塔形的。
So in terms of the first step of skeletal structure, this is actually going to be easier because we don't have a central atom, we just have carbon and nitrogen here.
对于第一步画出骨架，其实比刚才更容易,因为我们没有一个中心原子，我们这里只有碳和氮两个原子。
