Naming coordination complex
1. Ligands
(1). Negative ions as ligands Ligand = Element’s root -o for example:
CN- Cyano F- Fluoro Cl- Chloro Br- Bromo O2- Oxo OH- Hydroxo NO2NO3CO32CH3COOH-O CCO 2 2 Nitro Nitrato Carbonato Acetato Hydrido Oxalato
络合物的命名 （Naming coordination complex）
命名时先命名阳离子部分，最后命名阴离子部分， 阴离子配体以字母顺序列出，中心阳离子价态一般 以罗马数字在名称后标出。
K[BF4] potassium tetrafluoroborate(III) K4[Fe(CN)6] potassium hexacyanoferrate(II) [Cu(NH3)4]SO4 Tetraamminecopper(II) sulfate [Co(H2O)2(NH3)2(CO3)]NO3 Diammine diaquacarbonatocobalt(III)nitrate
• 配合物是由中心离子或原子与配体之间通 过配位键结合而成的化合物。配体通过含 有孤对电子对的原子与中心离子成键。 • A coordination complex is a compound consisting of a central ion or atom combined to ligands through coordinate bond. • Ligands enter into bonds with the central ion or atom through atoms having/containing unshared electron pairs.

[Cu(NH3)4]SO4 Tetraamminecopper(II) sulfate
3
(2). Neutral molecules as ligand Ligand = Radical name for example: NH3 CO H2O CH3NH2 Ammine Carbonyl Aqua Methylamine
4
H2NCCNH2 Ethylenediamine
2. Complex ions
methylamine
6
(2).Complex ions with negative charge
Complex ion =n-Ligand-metal’s root-ate(N)
for example: [Fe(CN)6]4- Hexacyanoferrate(II) [BF4]Tetrafluoroborate(III)
[AlF6]3[AuCl4]-
Hexafluoroaluminate(III)
Tetrachloroaurate(III)
7
3.Naming complex
Complex = Cation + anion
for example:
Li[AlH4] [Ag(NH3)2]Cl K4[Fe(CN)6] Ni(CO)4 Lithium tetrahydroaluminate(III) Diamminesilver(I) chloride Potassium hexacyanoferrate(II) Tetracarbonylnickel(0)

常见配体的名称 ions CNOHCH3COOcyano hydroxo acetato molecules H2O NH3 CO aqua ammine carbonyl
NO3NO2FClBrC百度文库32-
nitrato nitro
fluoro chloro bromo carbonato
CH3NH2
(1). Neutral complex or complex ions with positive charge Complex ion = n-Ligand-metal ion(N) for example: Ag(NH3)2+ Diamminesilver(I)
Cu(NH3)42+ Tetraamminecopper(II) [Co(NH3)3(NO2)3] Triamminetrinitrocobalt(III)
