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.
