Using IUPAC norms write the systematic names of the following:

(i) [Co(NH3)6]Cl3


(ii) [Pt(NH3)2Cl(NH2CH3)]Cl


(iii) [Ti(H2O)6]3+


(iv) [Co(NH3)4Cl(NO2)]Cl


(v) [Mn(H2O)6]2+


(vi) [NiCl4]2–


(vii) [Ni(NH3)6]Cl2


(viii) [Co(en)3]3+


(ix) [Ni(CO)4]

(i) Starting with cation , the complex ion contains six ammonia molecules with cobalt in + 3 oxidation state. The name of compound: [Co(NH3)6]Cl3 is hexaamminecobalt(III) chloride.


(ii) The complex ion is cation, so there are 2 ammonia molecules, one chloride ion and methyammine molecule qith platinum in + 2 state. Going in alphabetical order, the name of compound: [Pt(NH3)2Cl(NH2CH3)]Cl is diamminechloridomethylammineplatinum(II) chloride.


(iii) It is a complex cation with six water molecules and titanium atom in + 3 state. The name of the compound: [Ti(H2O)6]3+ is hexaaquatitanium(III) ion


(iv) The complex ion is cation with cobalt in + 3 state and with four ammonia molecules i.e tetraammine, one chloride ion and nitrate ion. The name of the compound: [Co(NH3)4Cl(NO2)]Cl is tetraamminechloridonitritocobalt(III) chloride.


(v) The complex ion is cation with manganese in + 2 state and six water molecules. The name of compound: [Mn(H2O)6]2+ is hexaaquamanganese(II) ion.


(vi) The complex is anion with nickel in + 2 state and with four chloride ions. The name of the compound: [NiCl4]2– is tetrachloridonickeltate(II) ion.


(vii) The complex is cation with nickel in + 2 state and six ammonia molecules. The name of compound: [Ni(NH3)6]Cl2 is hexaamminenickel(II) chloride.


(viii) The complex is cation withcobalt in + 3 stateand there is a bidentate ligand called as ethylenediamine. The name of compound : [Co(en)3]3+ is tris(ethylenediamine)cobalt(III) ion.


(ix) It is neutral complex with four carbonyl molecules and cobalt in 0 state. The name of compound: [Ni(CO)4] is tetracarbonylcobalt(0).
