    The layered niobium oxysulfide was synthesized by the heat treatment of K4Nb6O17 · 3H2O layered oxide in the mixture of H2SZN2 gases. The layered oxysulfide had the large plate-like shape, and the total ratio of compound was estimated KxNbS2-yOy (The number of x was from 0.2 to 0.4, y was from about 0.5 to 1.0). According to the XPS measurement, the oxidation state of Nb was estimated for +2, +4, +5, and oxidation state of S was -2. It was confirmed that the layered oxysulfide has ion exchange, and intercalation capabilities as proton exchange reactions take place in H 2SO4 solution and bulky amine molecules can be intercalated in an amine solution.
