Reaction of Me(3)SiNSNSNSNSiMe(3) with [PPh(4)](2)[Pd2Cl6] resulted in a mixture of [PPh(4)][PdCl2(S2N3)] and [PPh(4)](2)[Pd2Cl4(S3N2)]; in addition to the analogous bromo species, reaction with [PPh(4)](2)[Pd2Br6] also generated [PPh(4)](2)[Pd2Br6(S2N2)]. The crystal structure of [PPh(4)][PdBr2(S2N3)], only the second full characterization of a complex of [S2N3](-), confirmed the presence of two distinct S-N bond lengths (1.49 and 1.6 Angstrom), while the N-15 NMR spectrum of partially N-15-labelled [PPh(4)][PdCl2(S2N3)] confirms the absence of protonation on the S-N ligand. Potential mechanisms for these reactions are discussed.
