[Ni(H₂O)₆]⁺² and [Fe(H₂O)₆]⁺³
The structure drawing is attached on the following pictures:
- Remember that complex is formed between Metal as Fe⁺³ or Ni⁺² in this case and ligand which may be neutral as H₂O & NH₃ or anion as I⁻ and CN⁻
- The charge of complex equal to the summation of total charges on metal and ligands.
