In the first Sm3+ site, Sm3+ is bonded in a 8-coordinate geometry to eight Te2- atoms. There are a spread of Sm–Te bond distances ranging from 3.17–3.54 Å. In the second Sm3+ site, Sm3+ is bonded in a 8-coordinate geometry to eight Te2- atoms. There are a spread of Sm–Te bond distances ranging from 3.17–3.47 Å. In the third Sm3+ site, Sm3+ is bonded to seven Te2- atoms to form distorted SmTe7 pentagonal bipyramids that share corners with two equivalent CrTe6 octahedra and edges with two equivalent SmTe7 pentagonal bipyramids. The corner-sharing octahedral tilt angles are 48°. There are a spread of Sm–Te bond distances ranging from 3.13–3.23 Å. In the fourth Sm3+ site, Sm3+ is bonded in a 8-coordinate geometry to seven Te2- and one Cl1- atom. There are a spread of Sm–Te bond distances ranging from 3.19–3.37 Å.
