BaSm2Te4 crystallizes in the orthorhombic Pnma space group. Ba(1) is bonded in a 8-coordinate geometry to two equivalent Te(1), two equivalent Te(2), two equivalent Te(3), and two equivalent Te(4) atoms. There are two inequivalent Sm sites. In the first Sm site, Sm(1) is bonded to one Te(3), two equivalent Te(1), and three equivalent Te(2) atoms to form a mixture of corner and edge-sharing SmTe6 octahedra. The corner-sharing octahedral tilt angles range from 47-61°. In the second Sm site, Sm(2) is bonded to one Te(1), two equivalent Te(3), and three equivalent Te(4) atoms to form a mixture of corner and edge-sharing SmTe6 octahedra. The corner-sharing octahedral tilt angles range from 47-61°. There are four inequivalent Te sites. In the first Te site, Te(1) is bonded to two equivalent Ba(1), one Sm(2), and two equivalent Sm(1) atoms to form a mixture of distorted corner and edge-sharing TeBa2Sm3 trigonal bipyramids. In the second Te site, Te(2) is bonded to two equivalent Ba(1) and three equivalent Sm(1) atoms to form a mixture of corner and edge-sharing TeBa2Sm3 square pyramids. In the third Te site, Te(3) is bonded to two equivalent Ba(1), one Sm(1), and two equivalent Sm(2) atoms to form a mixture of distorted corner and edge-sharing TeBa2Sm3 trigonal bipyramids. In the fourth Te site, Te(4) is bonded to two equivalent Ba(1) and three equivalent Sm(2) atoms to form a mixture of distorted corner and edge-sharing TeBa2Sm3 trigonal bipyramids.
