Nomenclature of complex compounds before 1930

1. discoverer(Magnus salt , Gmelin compound , and Zeise salt)

Vauquelin Salt : [Pd(NH3)4] [PdCl4]Magnus Salt : [Pd(NH3)4] [PtCl4]Gmelin Compound : [Co(NH3)6]2(C2O4)3

Zaise salt : K[PtCl3(C2H4)].H2O

2. Color ( Prussian blue , luteo complex , complex praseo )Prusia Blue (prusia blue) : KFe[Fe(CN)6].H2OLuteo Complex (yellow) : [Co(NH3)6Cl]Cl2

Praseo Complex (green) : [Co(NH3)4Cl2]

Nomenclature of complex compounds

• The name and number of the existing ligands as well as the name of the central atom and its degree of oxidation

[Fe(NH3)4(CN)2]NO3 tetramindisianobesi(III)nitrat

• The name and number of ligands , the name of the central atom and the charge of the existing complex

[Fe(NH3)4(CN)2]NO3 = tetramindisianobesi(+1) nitrat

Naming Ligands(based on charged) • neutral ligand• negative ligand• Positive ligand (not common)

Writing ligand: Usually the donor atom is written section front, except for a few ligands; H2O, H2S, and H2Te

Neutral ligands are given the same name as the uncoordinated molecule, but with spaces omitted.Some neutral molecules, when serving as ligands are given specialnames. These are:

Anionic ligands are given names that end in the letter “o”. When the name of the free, :When the name of the free, uncoordinated anion ends in “ide”, the ligand name ischanged to end in “ido”. Some examples are:

uncoordinated anion ends in “ate”, the ligand n ame is changed to end in “ato”.Some examples are

Ligands are often abbreviated name

Mention sequence Ligands

Name the ligands first, in alphabetical order, then the metal atom or ion. (Holtzclaw dan Robinson,1988:769;IUPAC,1994 :151)

• The sequence suggested that the ligand mention of the alphabet used as a basis in the order mentioned ligand is the ligand name after Indonesianized.

• The amount of ligand that is expressed by the prefix in, tri, tetra, etc.

• If the prefix has been used to refer to the existing number of substituents on the ligand, the amount of ligand expressed by prefixes bis, tris, tetrakis, and so on.

• Ligand consisting of two or more atoms written in parentheses

examples:

[Co(en)2Cl2]+

•ion bis(etilendiamin)diklorokobalt(III)

Nomenclature Neutral Complex Compound

1) Name of neutral complex compounds written in one word.2) Write or mention the name and number of ligands3) Write or mention the name of the central atom and the

oxidation state of the central atom is written in Roman numerals. And the oxidation number of the central atom zero price does not need to be written

• Cation complex compoundsCation complex compounds nomenclature as ion complex

follow this rules:1) Beginning with writing or mention the word ion2) Write or mention the name and number of ligand-owned3) Write or mention central atom name followed oxidation number is written in Roman numerals.

Besides the above nomenclature can be write in the following way :1) Beginning with writing or mention the word ion2) Write or mention the name and number of ligand-owned3) Write or mention the name and the charge of the complex ion that is written in Arabic numerals.

• Name of anion ComplexExpressed with ion followed by

the name and number of ligands, the name of the central atom in Latin ending by -ium -um or replaced with -at as well as the oxidation state of the central atom is written with Roman numerals• (---- Arabic numbers)

• Ionic complex compounds composed of cations and anions. One can be a complex ion.

• Ionic complex compound name written in two words, first called the name of the cation, followed by the name of the anionexamples:

=> diamminesilver (I) chloride, [Ag(NH)2] Cl=> potassium hexacyanoferrate (III), K3[Fe(CN)6]

Complex compound that have isomer

• Nama senyawa ditambah dengan awalan yang menyatakan isomer misalnya : -cis, -trans, fac, mer dll

• Nomenclatur of the compound

Cis-diamminedichloroplatinum (II) Trans-diamminedichloroplatinum (II)

fac-[Ru(H2O)3Cl3]

fac-triaquotrichlororutenium (III)

mer-[Ru(H2O)3Cl3]

mer-triaquotrichlororutenium (III)

Nomenclature of complex compounds with ligands bridge

• bridging ligand is a ligand donor atoms can bind two or more atomic centers

• ligands bridge should not the same compound

[(NH3)5Cr-OH-Cr(NH3)5]Cl5

• Ion µ-hidroksobis-[pentaaminakromium(III)• Ion µ-hidroksobis-[pentaaminakromium(+5)

nomenclature of complex compounds with ligands bridge

• [(MeCN)2Li(µ-I)2Li(NCMe)2]• µ-iodobis[diasetonitrillitium(I)]

nomenclature of complex compounds with ligands bridge

• [(NH3)4Co(µ-NH2)(µ-SO2)Co(NH3)4]• Ionµ-amiso-µsulfonilbis[tetraaminakobal(II)]

Complex compounds with Polydentate ligands

Tris(ethylenediamine)cobalt(III)

• Complex ion [Co(en)3]3+ contains three ligands ethylenediamine. The complex ions formed octahedral coordination structure with atoms of cobalt (III) as the central atom

Compound Complex with two of the central atom bind to each other

• [Br4Re-ReBr4]2-

ion bis [tetrabromorenat(III)(Re-Re) atau ion bis[tetrabromorenat(Re-Re)(2-)]

• [(CO)5Mn-Mn(CO)5]

bis(pentakarbonilmangan)(Mn-Mn)

• [(CO)4Co-Re(CO)5]

pentakarbonil(tetrakarbonilkobaltio)renium (Co-Re)

Unsaturated ligand name

• was given the prefix N- (Hapto), while the number of atoms involved in the system is not saturated expressed numerically rank the prefix n-, ŋ5- prefix is used when there are 5 atoms involved in the system is not saturated as the ligand C5H5 (cyclopentadienyl). If there are two atoms involved in the system is not saturated used early N- or ŋ2-.

examples:Cis - [Pt (NH3)(C2H4) Cl2].• Cis-amina(ŋ-etilena)dikloroplatina(II).

Meta-losena• Complex bis (n5-cyclopentadienyl) metal

complex is also called meta-losena• M = Fe :ferosena

Mn : manganosena Co :kobaltosenaNi :nikelosena

• Groups existing branches are numbered at the lowest price. The carbon atom in the first ring are numbered 1 to 5, while on the other ring are numbered 1 'to 5'.
