in solid state pcl5 prefer to exist as oppositely charged ions like [pcl4]- and [pcl6]- as the ionic bonding enhances the crystalline nature .
also [pcl4]- is tetrahedral , while [pcl6]- is octahedral . these structure fit well into each other providing extra stability to solid structure .

Pcl5 is quite unstable due to electronic repulsion at axial bond. So to gain stability it decomposes to cation and anion.

Its [PCl4]+ and [PCl6]-

not[PCl4]- and [Pcl6]- the above given answer is wrong

hope now it has cleared doubt

Hello Student

In solid state PCl₅ exist in ionic form.

it exist as a diamer .

i.e. [PCl₄]⁺ [PCl₆]^-in which [PCl₄]⁺ is tetrahedral and [PCl₆]^- is octahedral.

Because PCl₅ is quite unstable due to electronic repulsion at axial bond. So these structure fit well into each other providing extra stability to solid structure.

I hope this answer will help you.
