The crystal structure described by Sm2CuTe4 crystallizes in the monoclinic P2_1 space group. There are two inequivalent Sm sites. In the first Sm site, Sm(1) is bonded in a 10-coordinate geometry to two equivalent Cu(1), two equivalent Te(1), two equivalent Te(2), two equivalent Te(3), and two equivalent Te(4) atoms. In the second Sm site, Sm(2) is bonded in a 9-coordinate geometry to one Cu(1), two equivalent Te(1), two equivalent Te(2), two equivalent Te(3), and two equivalent Te(4) atoms. Cu(1) is bonded in a 7-coordinate geometry to one Sm(2), two equivalent Sm(1), one Te(2), one Te(3), and two equivalent Te(1) atoms. There are four inequivalent Te sites. In the first Te site, Te(1) is bonded in a 6-coordinate geometry to two equivalent Sm(1), two equivalent Sm(2), and two equivalent Cu(1) atoms. In the second Te site, Te(2) is bonded in a 5-coordinate geometry to two equivalent Sm(1), two equivalent Sm(2), and one Cu(1) atom. In the third Te site, Te(3) is bonded in a 5-coordinate geometry to two equivalent Sm(1), two equivalent Sm(2), and one Cu(1) atom. In the fourth Te site, Te(4) is bonded in a 4-coordinate geometry to two equivalent Sm(1) and two equivalent Sm(2) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
