The compound described by K2(CuTe)5 crystallizes in the orthorhombic Cmcm space group. K(1) is bonded in a distorted body-centered cubic geometry to two equivalent Te(1), two equivalent Te(2), and four equivalent Te(3) atoms. There are three inequivalent Cu sites. In the first Cu site, Cu(1) is bonded in a 4-coordinate geometry to two equivalent Te(1) and two equivalent Te(2) atoms. In the second Cu site, Cu(2) is bonded in a 4-coordinate geometry to one Te(2) and three equivalent Te(3) atoms. In the third Cu site, Cu(3) is bonded to one Te(1), one Te(3), and two equivalent Te(2) atoms to form distorted corner-sharing CuTe4 tetrahedra. There are three inequivalent Te sites. In the first Te site, Te(3) is bonded in a 8-coordinate geometry to four equivalent K(1), one Cu(3), and three equivalent Cu(2) atoms. In the second Te site, Te(1) is bonded in a 8-coordinate geometry to four equivalent K(1), two equivalent Cu(1), and two equivalent Cu(3) atoms. In the third Te site, Te(2) is bonded in a 6-coordinate geometry to two equivalent K(1), one Cu(1), one Cu(2), and two equivalent Cu(3) atoms. is represented by the CIF card [CIF]
