The reaction of chloro­di­thio­phoshoric acid pyridinium betaine, PyPS2Cl, with 2,3‐di­amino­naphthalene yields the title compound, (PyH)(C10H8N2)PS2 or C5H6N+·C10H8N2PS2−. The P atom is coordinated by both N atoms of 2,3‐di­amino­naphthalene with the formation of a five‐membered ring.

The title Pd complex, [Pd(C6H14N3S)(CH3O2PS2)], is formed from Pd(acetate)2 and 5‐tert‐butyl­amino‐4‐methyl‐2‐sulfido‐2‐thio­xo‐1,3,4,2λ5‐thia­di­aza­phospho­lan‐5‐onium, (1), in meth­anol. The Pd atom is coordinated to two different ligands which are generated in situ as a result of methano­lysis of the starting compound (1). Thus, Pd is complexed by the O‐methyl­di­thio­phosphate ligand and by 2‐methyl‐4‐tert‐butyl­thio­semicarbazide. Two mol­ecules of the Pd chelate are linked by two intermolecular N—H⋯O hydrogen bonds, the N⋯O distances of which are 3.361 and 2.827 Å.
