The structure described by YbTb2S4 crystallizes in the tetragonal I-42d space group. Yb(1) is bonded in a 8-coordinate geometry to eight equivalent S(1) atoms. Tb(1) is bonded in a 8-coordinate geometry to eight equivalent S(1) atoms. S(1) is bonded to two equivalent Yb(1) and four equivalent Tb(1) atoms to form a mixture of distorted edge, face, and corner-sharing STb4Yb2 octahedra. The corner-sharing octahedral tilt angles range from 18-50°. is represented by the CIF file [CIF]
