# Solution check for Complex Molecule IUPAC Naming

• Chemistry

## Homework Statement

a) Given the IUPAC name to the chemical formulas: $${\left[ {Ni{{\left( {N{H_3}} \right)}_6}} \right]^{2 + }}$$ $$\left[ {CrC{l_3}{{\left( {N{H_3}} \right)}_3}} \right]$$ $${\left[ {Co{{\left( {N{O_2}} \right)}_6}} \right]^{3 - }}$$

b) Give the metal oxidation state, Coordination number and distinguish the donar atoms for each complex.

2. The attempt at a solution
$${\left[ {Ni{{\left( {N{H_3}} \right)}_6}} \right]^{2 + }}{\rm{ - hexaaminenickate ion}}\left( {II} \right)$$ CN - 6, Metal oxidation state - 2+

$$\left[ {CrC{l_3}{{\left( {N{H_3}} \right)}_3}} \right]{\rm{ - trisaminetriclorocromate}}\left( {III} \right)$$ CN - 6, Metal oxidation state - 3+

$${\left[ {Co{{\left( {N{O_2}} \right)}_6}} \right]^{3 - }}{\rm{ - hexanitrocobalt}}\left( {III} \right){\rm{ ion}}$$ CN - 6, Metal oxidation state 3+

are these soluions correct?
