ionic, [PCl4]+ [PCl6]-
I believe that it is ionic because PCl5 loses a Cl- ion, and you have two charged parts: PCl4+ and Cl-. wikipedia says PCl4+ PCl6- this is correct- the reason that the molecular form is not favored is probably explained by the substantial "gain" in lattice energy moving to an ionic form from a molecular form with weak intermolecular bonds. Also packing of the PCl5 molecules would be less efficient compared to that of the ionic solid with a mix of 4 and 6 coordinate species.
The structures for the phosphorus chlorides are invariably consistent with VESPER theory. The structure of PCl5 depends on its environment. Gaseous and molten PCl5 is a neutral molecule with trigonal bipyramidal . The hypeRVALENT nature of this species can be explained with three-center four-electron bonding model. This trigonal bipyramidal structure persists in non-polar solvents, such as CS2 and CCl4.In the solid state PCl5 is ionic, formulated PCl4+ PCl6−.
The decomposition reaction for PCl5 is represented as follows: PCl5 (s) → PCl3 (g) + Cl2 (g). This reaction involves the breaking down of solid phosphorus pentachloride (PCl5) into gaseous phosphorus trichloride (PCl3) and chlorine gas (Cl2). The reaction is endothermic, requiring energy input to break the bonds within the PCl5 molecule.
The oxidation state of phosphorus (P) in PCl5 is +5. Each chlorine atom has an oxidation state of -1, and since there are 5 chlorine atoms in PCl5, the total charge contributed by chlorine is -5. To balance this, the oxidation state of phosphorus must be +5.
The solid state of water - is... ice.

There are three states of matter, solid, liquid and gas. The state of matter wherein particles are fixed in a rigid structure is solid.
The oxidation state of phosphorus (P) in PCl5 is +5. Each chlorine atom has an oxidation state of -1, and since there are 5 chlorine atoms in PCl5, the total charge contributed by chlorine is -5. To balance this, the oxidation state of phosphorus must be +5.
The oxidation state of phosphorus in PCl5 is +5. Each chlorine atom contributes an oxidation state of -1, so the sum of the oxidation states in PCl5 equals the overall charge of the molecule, which is 0.

Phosphorus pentachloride (PCL5)
The oxidation state of phosphorous in PCl5 is +5.The valence shell has 5 electrons.It therefore cannot increase its oxidation state more than 5.Therefore PCl5 cannot act as a reducing agent as it cannot donate electrons.The oxidation state can be decreased to +3 by gaining electrons. There for PCl5 can act as a oxidizing agent.A example is given below along with the change in oxidation states of phosphorous.
In the solid PCl5 is ionic PCl4+ PCl6- In the gas and liquid phases molecular PCl5 is present which does not have a permanent dipole moment. The intermolecular force is a london dispersion force.
MgCl2 is an ionic compound that forms a crystal lattice structure in its solid state. It is a white crystalline solid with a high melting point.
