1、Some common ligands:F-，Cl-，Br-，I-，O2-，N3-，S2-，OH-，CN-，H-，-NO2-，-ONO-，SO42-，C2O42-，SCN-，NCS-，N3-，O22-，N2，O2，NH3，CO，NO，H2O，en，ph3PNomenclature of the coordination complex1.Add the word“hua”or“suan”between inside of the complex and the outside.Such as:Co(NH3)6 Cl3 trichloride“hua”hexaammine cobalt(III)

2、Cu2 Si F6 hexafluorosilicate“suan”cuprous2.In the coordination unit,the ligand is first followed by the center.Using two,three,four,and so on,in front of the ligand shows the number of ligands,where the different ligands are separated by dot,and the ligand and the center atoms have to be put the wor

3、d“he”in between.The brackets should be added after the center,where roman number in the bracket shows the valence of ion.3.The sequences of ligands(1)Inorganic one is firstly named and then organic(2)anions is firstly named and then moleculesSuch as:KPtCl3(C2H4)：trichlorid ethylene“he”palatinate(II)

4、“suan”potassium(3)If theyre both molecules or ions,their nomenclature should be represented in alphabetical order according to the symbols of coordination atomic elements.Such as:Co(NH3)5H2OCl3：Chloride“hua”pentamonium hydrate“he”cobalt(III)(4)In the same kind of ligands,according to the order of co

5、ordination atoms in the English alphabet.(5)If the coordination atoms are the same,the ones that have fewer atoms in the ligand should be put in front.(6)If the number of atoms are the same,other atoms directly connected with ligand atom present alphabetically.Such as:PtNH2NO2(NH3)2:amino nitrocellulose diamine“he”platinum()
