Arsenic monophosphide

Arsenic monophosphide, also called arsenic phosphide, 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.

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.

Structure
The structure of AsP is a two-dimensional mono layer composed of an equimolar mixture of phosphorus and arsenic.

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