The ICl4−\text{ICl}_4^-ICl4− ion contains two different Group 7 elements.
Use your understanding of electron pair repulsion theory to:
Draw or describe the shape of this ion, including any lone pairs of electrons on the central iodine atom that influence the shape.
Explain why the ion has the shape you have drawn/described.
Suggest a value for the Cl-I-Cl\text{Cl-I-Cl}Cl-I-Cl bond angle.
