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]
