---------------------------------------------------

 

[Rule 1]

> For positive complex, the complex is named first

before naming the negative counter ion (anion).

> For negative complex, the positive counter ion (cation) is named first

if present, followed by the complex.

> 양이온을 먼저 명명하는 이온 결합 화합물의 명명법과 동일하다.

예 1) [Co(NH3)6]Cl3: Hexamminecobalt(III) chloride

예 2) K2[Ni(CN)4]: Potassium tetracyanonickelate(II)

 

 

 

 

[Rule 2]

> In the coordination sphere, the ligands are named

before the metal in alphabetical order of the ligands’ names,

however the metal ion is written first in formula.

> The coordination sphere is enclosed in square brackets in the formula.

> 알파벳순으로 리간드를 먼저 명명한다.

 

예 1) [Cu(NH3)4(H2O)2]SO4: Tetraamminediaquacopper(II) sulphate

예 2) [Co(NH3)5Cl]Cl2: Pentaamminechlorocobalt(III) chloride

예 3) [Co(N3)(NH3)5]SO4: Pentaammineazidocobalt(III) sulfate

 

 

 

 

[Rule 3]

> The number of ligands in a complex is indicated

by one or both of the prefixes listed below.

 

Number	First prefix	Second prefix
2 3 4 5 6 7 8 9 10	Di Tri Tetra Penta Hexa Hepta Octa Nona Deca	Bis Tris Tetrakis Pentakis Hexakis Heptakis Octakis Nonakis Decakis

it is enclosed in parenthesis and the second set of prefix is used.

예 2) [Fe(NH4C5-C5H4N)3]Cl2: Tris(bipyridine)iron(III) chloride

 

 

 

 

[Rule 4]

> Anionic ligands e.g. Br^-, Cl^-, F^-, SO4^2- etc are named

with a suffix “o” while neutral ligands retained their usual name

except H2O called aqua, NH3 called ammine.

> Note also that the name of the metal in an anionic complex

ends with a suffix “ate”.

 

예 1) K4[Fe(SCN)6]: Potassium hexathiocyanatoferrate(II)

예 2) [Ni(C2O4)2]^2-: Bis(oxalato)nickelate(II)

예 3) K[Au(CN)2] Potassium dicyanoaurate(I)

 

 

 

 

[참고] 음이온 착물에서 금속의 이름

> iron: ferrate

> copper: cuprate

> lead: plumbate

> silver: argentate

> gold: aurate

> tin: stannate
