Except for Ln=Eu and Lu, single-phase samples were prepared. The compounds consist of an alternate stacking of a trigonal prism-type [NbS2] layer and a double-layered NaCl [rock salt (RS)]-type [Ln2S2] block, parallel to the c-axis. Three types of stacking modes of the [NbS2] layer and the RS-type block have been confirmed with a (3+1)-dimensional superspace group description: two face-centered orthorhombic structures and one face-centered monoclinic structure. Slightly cation-deficient samples with Ln=Yb exhibit the highest Seebeck coefficient S≈59μV/K. With electrical resistivity of $$\rho = 1.4 \,\hbox{m}{\Upomega}$$ ρ = 1.4 m Ω cm and thermal conductivity of κ=0.69W/Km, this yields a dimensionless figure of merit of ZT=0.11at 300K.
