EuCuSF 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 S(1) and four equivalent F(1) atoms. Cu(1) is bonded to four equivalent S(1) atoms to form a mixture of corner and edge-sharing CuS4 tetrahedra. S(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.
