Abstract

Two series of [(Ln1/3Sr2/3S)1.5]1.15NbS2and (Ln1-xSrxS)1+yNbS2misfit layer sulfides have been synthesized and studied by X-ray powder and single crystal diffraction, electron diffraction, and EDX-analysis. The [(Sm1/3Sr2/3S)1.5]1. 15NbS2compound belongs to the 1.5Q/1H homologue type where the Sr-cations are mainly located at the exterior of the Q-slab whereas Sm preferably occupy the positions at its center. The (Pr0.55Sr0.45S)1.15NbS2sulfide is a member of the 1Q/1H homologue series where almost half of the Pr-atoms in the Q-slab are replaced by Sr ones with a statistical distribution of Pr and Sr over the cation positions.
