The material structure described by Cu2SnTe3 is Enargite-like structured and crystallizes in the orthorhombic Imm2 space group. Cu(1) is bonded to one Te(2) and three equivalent Te(1) atoms to form CuTe4 tetrahedra that share corners with five equivalent Sn(1)Te4 tetrahedra and corners with seven equivalent Cu(1)Te4 tetrahedra. Sn(1) is bonded to two equivalent Te(1) and two equivalent Te(2) atoms to form SnTe4 tetrahedra that share corners with two equivalent Sn(1)Te4 tetrahedra and corners with ten equivalent Cu(1)Te4 tetrahedra. There are two inequivalent Te sites. In the first Te site, Te(2) is bonded to two equivalent Cu(1) and two equivalent Sn(1) atoms to form TeCu2Sn2 tetrahedra that share corners with two equivalent Te(2)Cu2Sn2 tetrahedra and corners with ten equivalent Te(1)Cu3Sn tetrahedra. In the second Te site, Te(1) is bonded to three equivalent Cu(1) and one Sn(1) atom to form TeCu3Sn tetrahedra that share corners with five equivalent Te(2)Cu2Sn2 tetrahedra and corners with seven equivalent Te(1)Cu3Sn tetrahedra. is represented by the CIF file [CIF]
