    Abstract

    Solid-state NMR has been used to study the local coordination environments of the protons and alkali metal cations in hydrated alkali metal intercalation compounds of MoS2, Ax(H2O)yMoS2 (A = Li, Na, K, Cs). The dynamic behavior of the water molecules, which are coordinated to the intercalated A+ cations, is consistent with an ordered quasi two-dimensional translational motion at room temperature. In Lix(H2O)yMoS2, the hydrated Li+ cations occupy two distinct sites in the van der Waals gap that are connected by dynamic processes. Partially random motions of the H2O molecules are activated at room temperature.
