When phosphorus reacts with excess chlorine gas, the compound phosphorus pentachloride (PCl5) is formed. In the gaseous and liquid states, this substance consists of PCl5 molecules, but in the solid state it consists of a 1:1 mixture of PCl4 1 and PCl6 2 ions. Predict the geometric structures of PCl5, PCl4 1, and PCl6 2.
