Question

Using IUPAC norms write the systematic names of the following:
i.$\left[ {Co{{\left( {N{H_3}} \right)}_6}} \right]C{l_3}$
ii.$\left[ {Pt\left( {N{H_3}} \right)Cl\left( {N{H_2}C{H_3}} \right)} \right]Cl$
iii.${\left[ {Ti{{\left( {{H_2}O} \right)}_6}} \right]^{3 + }}$
iv.$\left[ {Co{{\left( {N{H_3}} \right)}_4}Cl\left( {N{O_2}} \right)} \right]Cl$
v.${\left[ {Mn{{\left( {{H_2}O} \right)}_6}} \right]^{2 + }}$
vi.${\left[ {NiC{l_4}} \right]^{2 - }}$
vii.$\left[ {Ni{{\left( {N{H_3}} \right)}_6}} \right]C{l_2}$
viii.${\left[ {Co{{\left( {en} \right)}_3}} \right]^{3 + }}$
ix.$\left[ {Ni{{\left( {CO} \right)}_4}} \right]$

Answer 1

Complex compounds can also be known as coordination compounds. It contains a coordination sphere and an ionization sphere. The coordination sphere consists of a metal ligand. The ionization sphere consists of other atoms or groups. The oxidation state indicated in the brackets with a roman number.

Complete answer:
Complex compounds are defined as the special type of compounds that can retain their identity even dissolved in water or any other organic solvents. Complex compounds cannot give the tests for the atoms present in it.
The naming of the IUPAC nomenclature can be written as
The ligands should be written firstly followed by metal atoms. Metal atoms with roman numbers in brackets can be indicated. The oxidation state can be calculated from all the atoms and charge of the coordination sphere.
i.The metal atom is cobalt and the systematic name is hexaamminecobalt (III) chloride.
ii.The metal atom is platinum and the systematic name is diammine dichloride(methylamine)Platinum (II) chloride.
iii.The metal atom is titanium and the systematic name is hexaaquatitanium (III) ion.
iv.The metal atom is cobalt and the systematic name is tetramine chloride nitrito-N-Cobalt (III) chloride.
v.The metal atom is manganese and the systematic name is hexaaquamanganese (II) ion.
vi.The metal atom is nickel and the systematic name is tetrachloronickelate (II) ion.
vii.The metal atom is nickel and the systematic name is hexaamminenickel (II) chloride.
viii.The metal atom is cobalt and the systematic name is tris(ethane- $1,2$-diamine)Cobalt (III) ion.
ix.The metal atom is nickel and the systematic name is tetracarbonylnickel($0$ ).

Note:
The oxidation state can be indicated in brackets as a roman number. If the coordination sphere is anionic, then the metal atom should end with -ate. If the coordination sphere has a charge, the name of the complex should end with ion.
