The structure described by EuCuTeF is Parent of FeAs superconductors structured and crystallizes in the tetragonal P4/nmm space group. Eu(1) is bonded in a 4-coordinate geometry to four equivalent Te(1) and four equivalent F(1) atoms. Cu(1) is bonded to four equivalent Te(1) atoms to form a mixture of distorted corner and edge-sharing CuTe4 tetrahedra. Te(1) is bonded in a 8-coordinate geometry to four equivalent Eu(1) and four equivalent Cu(1) atoms. F(1) is bonded to four equivalent Eu(1) atoms to form a mixture of corner and edge-sharing FEu4 tetrahedra. is represented by the CIF card [CIF]
