NaPrS2 is Caswellsilverite-like structured and crystallizes in the tetragonal I4_1/amd space group. Na(1) is bonded to six equivalent S(1) atoms to form NaS6 octahedra that share corners with two equivalent Pr(1)S6 octahedra, corners with four equivalent Na(1)S6 octahedra, edges with four equivalent Na(1)S6 octahedra, and edges with eight equivalent Pr(1)S6 octahedra. The corner-sharing octahedral tilt angles range from 0-5°. Pr(1) is bonded to six equivalent S(1) atoms to form PrS6 octahedra that share corners with two equivalent Na(1)S6 octahedra, corners with four equivalent Pr(1)S6 octahedra, edges with four equivalent Pr(1)S6 octahedra, and edges with eight equivalent Na(1)S6 octahedra. The corner-sharing octahedral tilt angles range from 0-5°. S(1) is bonded to three equivalent Na(1) and three equivalent Pr(1) atoms to form a mixture of corner and edge-sharing SNa3Pr3 octahedra. The corner-sharing octahedral tilt angles range from 0-5°.
