Sr(PrS2)2 crystallizes in the tetragonal I-42d space group. Sr(1) is bonded to eight equivalent S(1) atoms to form distorted SrS8 hexagonal bipyramids that share corners with eight equivalent Pr(1)S8 hexagonal bipyramids, edges with four equivalent Sr(1)S8 hexagonal bipyramids, and faces with eight equivalent Pr(1)S8 hexagonal bipyramids. Pr(1) is bonded to eight equivalent S(1) atoms to form distorted PrS8 hexagonal bipyramids that share corners with four equivalent Sr(1)S8 hexagonal bipyramids, corners with four equivalent Pr(1)S8 hexagonal bipyramids, edges with four equivalent Pr(1)S8 hexagonal bipyramids, faces with four equivalent Sr(1)S8 hexagonal bipyramids, and faces with four equivalent Pr(1)S8 hexagonal bipyramids. S(1) is bonded to two equivalent Sr(1) and four equivalent Pr(1) atoms to form a mixture of distorted corner, edge, and face-sharing SSr2Pr4 octahedra. The corner-sharing octahedral tilt angles range from 16-51°.
