Chemical compound

Calcium arsenide is an inorganic compound with the chemical formula Ca₂As₂ and is one of the arsenides of calcium.^[1] It is a hexagonal crystal with a space group of P62m. It is isostructural with sodium peroxide and can be expressed as (Ca²⁺)₂(As-As)⁴⁻.^[2] It reacts with sodium monoarsenide and silicon in a tantalum container to obtain Na₄Ca₂SiAs₄.^[3] It reacts with potassium arsenide, iron arsenide and calcium fluoride at high temperature to obtain KCa₂Fe₄As₄F₂.^[4]
