Cd4PbTe5 is Enargite-like structured and crystallizes in the orthorhombic Imm2 space group. There are two inequivalent Cd sites. In the first Cd site, Cd(1) is bonded to one Te(2), one Te(3), and two equivalent Te(1) atoms to form CdTe4 tetrahedra that share corners with three equivalent Cd(1)Te4 tetrahedra, corners with four equivalent Pb(1)Te4 tetrahedra, and corners with five equivalent Cd(2)Te4 tetrahedra. In the second Cd site, Cd(2) is bonded to one Te(1) and three equivalent Te(2) atoms to form CdTe4 tetrahedra that share  a cornercorner with one Pb(1)Te4 tetrahedra, corners with five equivalent Cd(1)Te4 tetrahedra, and corners with six equivalent Cd(2)Te4 tetrahedra. Pb(1) is bonded to two equivalent Te(1) and two equivalent Te(3) atoms to form PbTe4 tetrahedra that share corners with two equivalent Cd(2)Te4 tetrahedra, corners with two equivalent Pb(1)Te4 tetrahedra, and corners with eight equivalent Cd(1)Te4 tetrahedra. There are three inequivalent Te sites. In the first Te site, Te(1) is bonded to one Cd(2), two equivalent Cd(1), and one Pb(1) atom to form TeCd3Pb tetrahedra that share corners with three equivalent Te(1)Cd3Pb tetrahedra, corners with four equivalent Te(3)Cd2Pb2 tetrahedra, and corners with five equivalent Te(2)Cd4 tetrahedra. In the second Te site, Te(2) is bonded to one Cd(1) and three equivalent Cd(2) atoms to form TeCd4 tetrahedra that share  a cornercorner with one Te(3)Cd2Pb2 tetrahedra, corners with five equivalent Te(1)Cd3Pb tetrahedra, and corners with six equivalent Te(2)Cd4 tetrahedra. In the third Te site, Te(3) is bonded to two equivalent Cd(1) and two equivalent Pb(1) atoms to form TeCd2Pb2 tetrahedra that share corners with two equivalent Te(3)Cd2Pb2 tetrahedra, corners with two equivalent Te(2)Cd4 tetrahedra, and corners with eight equivalent Te(1)Cd3Pb tetrahedra.
