Potassium tetracyanonickelate reacts with elemental sulfur and KOH in DMF to give the [(NC)2NiS5]2− anion, which has been isolated as its PPh4+ and AsPh4+ salts. The XPS S(2p) binding energies of the S5 ring sulfur are in the ratio 2(162.8 eV)/3(163.6 eV). Cyclic voltammetry shows that the compound undergoes an irreversible reduction at −1.825 V.
