The corner-sharing octahedral tilt angles range from 55-62°. In the fourth S site, S(4) is bonded to two equivalent Eu(1), one Sb(2), and two equivalent Sb(1) atoms to form distorted SEu2Sb3 trigonal bipyramids that share corners with five equivalent S(1)Eu2Sb4 octahedra, corners with three equivalent S(3)Eu2Sb3 square pyramids, corners with four equivalent S(4)Eu2Sb3 trigonal bipyramids, edges with three equivalent S(1)Eu2Sb4 octahedra, edges with two equivalent S(3)Eu2Sb3 square pyramids, and edges with four equivalent S(2)Eu2Sb3 trigonal bipyramids.
