Abstract

Water intercalated misfit-layer sulfides Na_x(H₂O)_y(SbS)_1+δ (TaS₂)₂ as well as parent compounds (SbS)_1+δTaS₂ and (SbS)_1+δ(TaS₂)₂ were found to exhibit superconductivity. The highest superconducting transition temperature of T_c = 3.5 K was observed in Na_x(H₂O)_y(SbS)_1+δ (TaS₂)₂ by intercalating a bilayer of water between adjacent TaS₂ layers. The transition temperature was reduced down to about 3 K by decreasing the water content y. This indicates that the presence of water is favorable to superconductivity in these sulfides.
