Arsenide chloride

Arsenide chlorides or chloride arsenides are compounds containing anions composed of chloride (Cl⁻) and arsenide (As³⁻). They can be considered as mixed anion compounds. They are in the category of pnictidehalides. Related compounds include the arsenide bromides, arsenide iodides, phosphide chlorides, and antimonide chlorides.
