Materials Data on BaCdAsF by Materials Project
BaFCdAs 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 As3- and four equivalent F1- atoms. All Ba–As bond lengths are 3.56 Å. All Ba–F bond lengths are 2.69 Å. Cd2+ is bonded to four equivalent As3- atoms to form a mixture of edge and corner-sharing CdAs4 tetrahedra. All Cd–As bond lengths are 2.82 Å. As3- 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.
