The crystal structure described by EuHfS3 is Orthorhombic Perovskite structured and crystallizes in the orthorhombic Pnma space group. Eu(1) is bonded in a 8-coordinate geometry to two equivalent S(1) and six equivalent S(2) atoms. Hf(1) is bonded to two equivalent S(1) and four equivalent S(2) atoms to form corner-sharing HfS6 octahedra. The corner-sharing octahedral tilt angles range from 33-35°. There are two inequivalent S sites. In the first S site, S(1) is bonded to two equivalent Eu(1) and two equivalent Hf(1) atoms to form distorted corner-sharing SEu2Hf2 trigonal pyramids. In the second S site, S(2) is bonded in a 5-coordinate geometry to three equivalent Eu(1) and two equivalent Hf(1) atoms. is represented by the CIF card [CIF]
