Statement - I :PCl₅ is covalent in gaseous and liquid states but ionic in solid state.
Statement - II :PCl₅ in solid state consists of tetrahedral ${\mathrm{PCl}}_4^{+}$ cation and octahedral ${\mathrm{PCl}}_6^{-}$ anion

In PCl₅, P has sp³d hybridization. In gaseous and liquid states, it act as a covalent solid.

But in solid state, it is an ionic compound that has two part, one is cationic part, ${\mathrm{PCl}}_4^{+}$ and another is anionic part, ${\mathrm{PCl}}_6^{-}$.]
