Zinc dialkyldithiophosphates (often referred to as ZDDP) are a family of coordination compounds developed in the 1940s that feature zinc bound to the anion of a dialkyldithiophosphoric salt (e.g., ammonium diethyl dithiophosphate). These uncharged compounds are not salts. They are soluble in nonpolar solvents, and the longer-chain derivatives easily dissolve in mineral and synthet… Thiophosphates (or phosphorothioates, PS) are chemical compounds and anions with the general chemical formula PS 4−xO x (x = 0, 1, 2, or 3) and related derivatives where organic groups are attached to one or more O or S.
