[IrCl₃(H₂O)₆]·3H₂O
Let's break down the formula:
* [IrCl₃(H₂O)₆] represents the complex ion:
* Ir³⁺ is the iridium(III) ion, carrying a +3 charge.
* Cl⁻ are three chloride ions, each carrying a -1 charge.
* (H₂O)₆ represents six water molecules coordinated to the iridium(III) ion. These water molecules are part of the inner coordination sphere.
* ·3H₂O represents three water molecules that are not directly coordinated to the iridium ion. These are water molecules of crystallization, present in the solid structure of the compound.
Therefore, the compound contains:
* One iridium(III) ion
* Three chloride ions
* Nine water molecules (six coordinated and three non-coordinated)
