Materials Data on BaCdSbF by Materials Project
BaCdSbF is Parent of FeAs superconductors structured and crystallizes in the tetragonal P4/nmm space group. The structure is three-dimensional. Ba2+ is bonded in a 4-coordinate geometry to four equivalent Sb3- and four equivalent F1- atoms. All Ba–Sb bond lengths are 3.70 Å. All Ba–F bond lengths are 2.72 Å. Cd2+ is bonded to four equivalent Sb3- atoms to form a mixture of edge and corner-sharing CdSb4 tetrahedra. All Cd–Sb bond lengths are 2.97 Å. Sb3- is bonded in a 8-coordinate geometry to four equivalent Ba2+ and four equivalent Cd2+ atoms. F1- is bonded to four equivalent Ba2+ atoms to form a mixture of edge and corner-sharing FBa4 tetrahedra.
