Materials Data on EuCuSeF by Materials Project
EuCuSeF is Parent of FeAs superconductors structured and crystallizes in the tetragonal P4/nmm space group. The structure is three-dimensional. Eu2+ is bonded in a 4-coordinate geometry to four equivalent Se2- and four equivalent F1- atoms. All Eu–Se bond lengths are 3.19 Å. All Eu–F bond lengths are 2.51 Å. Cu1+ is bonded to four equivalent Se2- atoms to form a mixture of corner and edge-sharing CuSe4 tetrahedra. All Cu–Se bond lengths are 2.53 Å. Se2- is bonded in a 12-coordinate geometry to four equivalent Eu2+ and four equivalent Cu1+ atoms. F1- is bonded to four equivalent Eu2+ atoms to form a mixture of corner and edge-sharing FEu4 tetrahedra.
