Tb2EuS4 crystallizes in the tetragonal I-42d space group. The structure is three-dimensional. Tb3+ is bonded to eight equivalent S2- atoms to form distorted TbS8 hexagonal bipyramids that share corners with four equivalent TbS8 hexagonal bipyramids, corners with four equivalent EuS8 hexagonal bipyramids, edges with four equivalent TbS8 hexagonal bipyramids, faces with four equivalent TbS8 hexagonal bipyramids, and faces with four equivalent EuS8 hexagonal bipyramids. There are a spread of Tb–S bond distances ranging from 2.77–3.05 Å. Eu2+ is bonded to eight equivalent S2- atoms to form distorted EuS8 hexagonal bipyramids that share corners with eight equivalent TbS8 hexagonal bipyramids, edges with four equivalent EuS8 hexagonal bipyramids, and faces with eight equivalent TbS8 hexagonal bipyramids. There are four shorter (2.88 Å) and four longer (3.06 Å) Eu–S bond lengths. S2- is bonded in a 6-coordinate geometry to four equivalent Tb3+ and two equivalent Eu2+ atoms.
