Abstract

The intercalation compound Kx(H2O)yMoS2 has been investigated by means of scanning tunneling microscopy. In contrast to 2H-MoS2, every Mo center in this compound is octahedrally surrounded by six sulfur ligands, whereas the hydrated K+ cations are located in the van der Waals gap between the layers. Analysis of the STM data showed that the surface structure within the (a,b) plane of Kx(H2O)yMoS2 is composed of parallel rows of sulfur atoms which are formed by sulfur ligands located at axial positions in the [MoS6] octahedra. Due to the distortion within the octahedra a wavy surface structure with an (a × a√3) superstructure is formed.
