Transition metal dithiophosphate complex

Transition metal dithiophosphate complexes are coordination compounds containing dithiophosphate ligands, i.e. ligands of the formula (RO)2PS
2
. The charge-neutral complexes tend to be soluble in organic solvents, especially when R is branched. Dithiophosphates are available with a wide variety of alkoxy groups. The range of complexes is similar to those for dithiocarbamate complexes.

Important members are zinc dialkyldithiophosphates, which are oil additives.
