Arsenic monophosphide explained

Arsenic monophosphide, also called arsenic phosphide,^[1] is an inorganic compound with the chemical formula AsP. Containing only arsenic and phosphorus, this material is classified as a binary phosphide as well as an interpnictogen. Ratios of arsenic to phosphorus are not fixed and can vary. Depending on the ratio, the band gap changes.^[2]

Synthesis

Arsenic monophosphide is synthesized through the reaction of the two pnictogens, arsenic and phosphorus, in a lead melt in sealed silica ampoules. The lead is removed by mixture of hydrogen peroxide and glacial acetic acid.^[3]

Structure

The structure of AsP is a two-dimensional mono layer composed of an equimolar mixture of phosphorus and arsenic.^[4]

Applications

Arsenic monophosphide is used in pharmaceuticals, preservatives, chemicals, treatments of leukemia, psoriasis, chronic bronchial asthma, and antibiotics.
