Boron arsenide (or Arsenic boride) is a chemical compound involving boron and arsenic, usually with a chemical formula BAs. Other boron arsenide compounds are known, such as the subarsenide B₁₂As₂. Chemical synthesis of cubic BAs is very challenging and its single crystal forms usually have defects.
