The material structure described by YbPrS3 crystallizes in the orthorhombic Cmcm space group. Yb(1) is bonded to two equivalent S(2) and four equivalent S(1) atoms to form a mixture of edge and corner-sharing YbS6 octahedra. The corner-sharing octahedral tilt angles are 68°. Pr(1) is bonded in a 8-coordinate geometry to two equivalent S(2) and six equivalent S(1) atoms. There are two inequivalent S sites. In the first S site, S(1) is bonded to two equivalent Yb(1) and three equivalent Pr(1) atoms to form distorted SYb2Pr3 square pyramids that share corners with nine equivalent S(1)Yb2Pr3 square pyramids, corners with four equivalent S(2)Yb2Pr2 tetrahedra, edges with six equivalent S(1)Yb2Pr3 square pyramids, and edges with three equivalent S(2)Yb2Pr2 tetrahedra. In the second S site, S(2) is bonded to two equivalent Yb(1) and two equivalent Pr(1) atoms to form SYb2Pr2 tetrahedra that share corners with eight equivalent S(1)Yb2Pr3 square pyramids, corners with four equivalent S(2)Yb2Pr2 tetrahedra, and edges with six equivalent S(1)Yb2Pr3 square pyramids. is represented by the Crystallographic Information File (CIF) [CIF]
