Ammonium dihydrogen phosphate Ammonium dihydrogen phosphate Ammonium dihydrogen phosphate (ADP), commonly called monoammonium phosphate (MAP) is a chemical compound with formula . It is a white crystalline solid consisting of ammonium cations and dihydrogen phosphate anions in equal proportions. ADP is a major ingredient of agricultural fertilizers and some fire extinguishers. It also has significant uses in optics and electronics. Monoammonium phosphate is soluble in water and crystallizes from it as the anhydrous salt in the tetragonal system, as elongated prisms or needles. It is practically insoluble in ethanol. Solid monoammonium phosphate can be considered stable in practice for temperatures up to 200
Dihydrogen bond via dihydrogen bonding. This kind of H−H interaction is distinct from the H−H bonding interaction in transition metal complexes having dihydrogen bound to a metal. So-called hydrogen hydrogen bond interactions have been proposed to occur between two neutral non-bonding hydrogen atoms from Atoms in molecules theory, while similar interactions have been shown to exist experimentally. Many of these types of dihydrogen bonds have been identified in molecular aggregates. Dihydrogen bond In chemistry, a dihydrogen bond is a kind of hydrogen bond, an interaction between a metal hydride bond and an OH or NH group or other proton donor. With a
