In chemistry, an arsenide is a compound of arsenic with a less electronegative element or elements. Many metals form binary compounds containing arsenic, and these are called arsenides. They exist with many stoichiometries , and in this respect arsenides are similar to phosphides .
Arsenic is used as the group 15 element in the III-V semiconductors gallium arsenide, indium arsenide, and aluminium arsenide. [10] The valence electron count of GaAs is the same as a pair of Si atoms, but the band structure is completely different which results in distinct bulk properties. [11]
Manganese arsenide (MnAs) is an intermetallic compound, an arsenide of manganese.It forms ferromagnetic crystals with hexagonal (NiAs-type) crystal structure, which convert to the paramagnetic orthorhombic β-phase upon heating to 45 °C (113 °F).
Arsenic is a common n-type dopant in semiconductor electronic devices. It is also a component of the III–V compound semiconductor gallium arsenide. Arsenic and its compounds, especially the trioxide, are used in the production of pesticides, treated wood products, herbicides, and insecticides. These applications are declining with the ...
Molybdenum diarsenide is an arsenide of molybdenum, with the chemical formula MoAs 2. Other arsenides of molybdenum are Mo 2 As 3 and Mo 5 As 4. [2] [3] Preparation.

Calcium arsenide is an inorganic compound with the chemical formula Ca 2 As 2 and is one of the arsenides of calcium. [1] It is a hexagonal crystal with a space group of P6 2 m. It is isostructural with sodium peroxide and can be expressed as (Ca 2+) 2 (As-As) 4−. [2] It reacts with sodium monoarsenide and silicon in a tantalum container to ...
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 B 12 As 2. Chemical synthesis of cubic BAs is very challenging and its single crystal forms usually have defects.
