Question

What is the molecular structure of $\left[\mathrm{Co}{\left({\mathrm{NH}}_3\right)}_6\right]{\mathrm{Cl}}_3$?

Answer 1

$\left[\mathrm{Co}{\left({\mathrm{NH}}_3\right)}_6\right]{\mathrm{Cl}}_3$

• The given compound is a coordination compound.
• In the given compound, cobalt $\left(\mathrm{Co}\right)$ metal is given.
• The ligand in the given compound is ammonia$\left({\text{NH}}_3\right)$. Ammonia is a neutral ligand.
• Three chloride ions are present outside the complex. So, the charge on the complex ion must be $+3$ (since the compound is electrically neutral).
