There's no single compound called "chlorine phosphate." The term is ambiguous. It could refer to several possibilities, depending on the intended oxidation state of chlorine and the number of chlorine atoms:

Possible interpretations:

* Phosphoryl chloride (POCl₃): This is the most likely compound referred to when someone says "chlorine phosphate." It's a colorless liquid used in chemical synthesis and is also known as phosphorus oxychloride.

* Chlorine-containing phosphates: There are also various phosphates containing chlorine atoms, such as:

* Chlorophosphate anions: These can be complex structures with varying numbers of chlorine and phosphate units.

* Chlorinated phosphate esters: These are organic compounds with chlorine atoms attached to the phosphate group.

To provide a specific chemical formula, you'd need to clarify the intended compound by providing more context. For example, specify:

* The oxidation state of chlorine (e.g., +1, +3, +5, etc.)

* The specific chlorine-containing phosphate group (e.g., PO₂Cl₂⁻)

* Any additional information regarding the structure or properties of the compound.

If you can provide more context, I can help you determine the exact chemical formula.
