The new dithiophosphate anion P 2 S 6 (OEt) 2 2– was obtained from the reaction of commercially available P 4 S 10 with Na 2 S in pyridine, subsequent ethanolysis and isolated as the stable bis(pyridinium) salt 1 . The molecular structure of 1 in the crystal was determined by single‐crystal X‐ray diffraction and reveals a PSSP dihedral angle of 87.3(1)° within the anion. The compound is a rare representative of a thiodiphosphate anion with a disulfide bridge between the two phosphorus atoms.
