The crystal structure described by Ge1Cu2Te3 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 Ge(1)Te4 tetrahedra and corners with seven equivalent Cu(1)Te4 tetrahedra. Ge(1) is bonded to two equivalent Te(1) and two equivalent Te(2) atoms to form GeTe4 tetrahedra that share corners with two equivalent Ge(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 Ge(1) atoms to form TeCu2Ge2 tetrahedra that share corners with two equivalent Te(2)Cu2Ge2 tetrahedra and corners with ten equivalent Te(1)Cu3Ge tetrahedra. In the second Te site, Te(1) is bonded to three equivalent Cu(1) and one Ge(1) atom to form TeCu3Ge tetrahedra that share corners with five equivalent Te(2)Cu2Ge2 tetrahedra and corners with seven equivalent Te(1)Cu3Ge tetrahedra. is represented by the Crystallographic Information File (CIF) [CIF]
