Statement 1: ${\mathrm{PCl}}_5$ is covalent in gaseous and liquid states but ionic in solid state.

Statement 2: ${\mathrm{PCl}}_5$ in solid state consists of tetrahedral ${\mathrm{PCl}}_4^{+}$ cation and octahedral ${\mathrm{PCl}}_6^{-}$ anion.

Both statements are true${\mathrm{PCl}}_5$ is trigonal bipyramidal containing ${\mathrm{PCl}}_4^{+}$ hybridized P atom in liquid and gaseous state.

Whereas in solid state it consists of tetrahedral ${\mathrm{PCl}}_4^{+}$ cation and octahedral ${\mathrm{PCl}}_6^{-}$ anion.
