Stacking disorder in 2H-NbS2 and its intercalation compounds Kx(H2O)yNbS2. II. Stacking disorder in Kx(H2O)yNbS2

摘要

The intercalation reaction of hydrated K+ions into the layered structure of 2H-NbS2 was studied using in situ X-ray diffraction. A structurally complex intercalation mechanism was observed showing several highly one-dimensionally disordered intercalated phases. A quantitative modelling of the disorder in Kx(H2O)yNbS2 is presented allowing a complete understanding of the intercalation mechanism.
