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