Na(0.88)Mn(0.56)PS(3)compounds have been synthesized by starting from MnPS3 polycrystalline powders by means of a two-step cation-exchange process at a higher intercalation time than the one used for producing the literature reported Na0.62Mn0.69PS3 compounds. The obtained samples have been characterized by X-ray photoelectron spectroscopy (XPS). The resulting spectra of the so-synthesized compounds have been compared with those observed in Na0.62Mn0.69PS3 in our previous paper and similar electronic properties have been noted. In particular by XPS it has been shown that greater sodium content affects neither the core-level binding energies of the host matrix elements nor the type of link between Na+ and (Mn1-xPS3)(-).
