In solid state it exists as (PCl4+ + Cl- ) ionic form

PCl5 is a covalent in gaseous and liquid states but ionic in solid state. Any specie will exist in what form? Depends on the condition in which it is placed and in any given condition it exists in that form which is most stable state at that condition. Now, as formation of ions are difficult in gaseous state, PCl5 is covalent in gaseous state (Remember: Charges cannot be stabilised in gaseous state) however, in solid state, ions can be stabilised by Lattice Energy, also in PCl5 two bonds (axial) are longer and three bonds are shorter (equatorial bonds) so PCl5 is nit that stable (reactive) in gaseous state, but in solid state as it can get more stabilised if it exists in ionic form, where it'll get additional stabilisation due to Lattice Energy it prefers to remain ionic in solid state! Hoping that this helped you!
