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. Thiophosphates feature tetrahedral phosphorus(V) centers. See more Organothiophosphates are a subclass of organophosphorus compounds that are structurally related to the inorganic thiophosphates. Common members have formulas of the type (RO)3−xRxPS and related compounds … See more The simplest thiophosphates have the formula [PS4−xOx] . These trianions are only observed at very high pH, instead they exist in protonated form with the formula … See more simple lighting circuit diagram uk system
