The crystal structure described by Eu2CuTe4 crystallizes in the tetragonal P-4m2 space group. Eu(1) is bonded in a 10-coordinate geometry to two equivalent Cu(1), two equivalent Te(2), two equivalent Te(3), and four equivalent Te(1) atoms. Cu(1) is bonded in a distorted body-centered cubic geometry to four equivalent Eu(1) and four equivalent Te(1) atoms. There are three inequivalent Te sites. In the first Te site, Te(1) is bonded in a 6-coordinate geometry to four equivalent Eu(1) and two equivalent Cu(1) atoms. In the second Te site, Te(2) is bonded in a 8-coordinate geometry to four equivalent Eu(1) and four equivalent Te(3) atoms. In the third Te site, Te(3) is bonded in a 8-coordinate geometry to four equivalent Eu(1) and four equivalent Te(2) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
