The correct answer is: ionic solid with $\left[\mathrm{PCl}_4\right]^{+}$and $\left[\mathrm{PCl}_6{ }^{-}\right.$
$\mathrm{PCl}_5$ is an ionic solid composed of $\left[\mathrm{PCl}_4\right]^{+}$ions
and $\left[\mathrm{PCl}_6\right]^{-}$ions. In an ionic solid, there is a transfer of electrons between atoms, resulting in the formation these cations and anions. These opposite charged ions held together by electrostatic forces forming a crystal lattice structure.
