SrPbS2 is Caswellsilverite structured and crystallizes in the trigonal R-3m space group. Sr(1) is bonded to six equivalent S(1) atoms to form SrS6 octahedra that share corners with six equivalent Pb(1)S6 octahedra, edges with six equivalent Sr(1)S6 octahedra, and edges with six equivalent Pb(1)S6 octahedra. The corner-sharing octahedral tilt angles are 1°. Pb(1) is bonded to six equivalent S(1) atoms to form PbS6 octahedra that share corners with six equivalent Sr(1)S6 octahedra, edges with six equivalent Sr(1)S6 octahedra, and edges with six equivalent Pb(1)S6 octahedra. The corner-sharing octahedral tilt angles are 1°. S(1) is bonded to three equivalent Sr(1) and three equivalent Pb(1) atoms to form a mixture of edge and corner-sharing SSr3Pb3 octahedra. The corner-sharing octahedra are not tilted.
