Materials Data on BaCdPF by Materials Project

Abstract

BaFCdP 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 P3- and four equivalent F1- atoms. All Ba–P bond lengths are 3.51 Å. All Ba–F bond lengths are 2.68 Å. Cd2+ is bonded to four equivalent P3- atoms to form a mixture of edge and corner-sharing CdP4 tetrahedra. All Cd–P bond lengths are 2.74 Å. P3- 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.
