The material described by Tb2EuS4 crystallizes in the tetragonal I-42d space group. Tb(1) is bonded in a 8-coordinate geometry to eight equivalent S(1) atoms. Eu(1) is bonded in a 8-coordinate geometry to eight equivalent S(1) atoms. S(1) is bonded to four equivalent Tb(1) and two equivalent Eu(1) atoms to form a mixture of distorted corner, face, and edge-sharing STb4Eu2 octahedra. The corner-sharing octahedral tilt angles range from 17-50°. is represented by the CIF card [CIF]
