When a coordination compound $\text{CoCl}_3\cdot 6\text{NH}_3$ is mixed with $\text{AgNO}_3$, three moles of $\text{AgCl}$ are precipitated per mole of the compound. Write the structural formula and IUPAC name of the coordination compound.
Answer
Answer
AI| IUPAC name | hexaamminecobalt(III) chloride |
| Formula | [Co(NH3)6]Cl3 |
Three moles of AgCl mean all three chloride ions are ionisable, so all six $\mathrm{NH_3}$ are in the coordination sphere: $[\mathrm{Co(NH_3)_6}]\mathrm{Cl_3}$.
