There are three inequivalent Te sites. In the first Te site, Te(1) is bonded in a 8-coordinate geometry to four equivalent K(1) and four equivalent Cu(1) atoms. In the second Te site, Te(2) is bonded in a 8-coordinate geometry to two equivalent K(1), two equivalent Eu(1), and four equivalent Te(2) atoms. In the third Te site, Te(3) is bonded in a 8-coordinate geometry to four equivalent Eu(1) and four equivalent Cu(1) atoms. is represented by the CIF card [CIF]
