BaFCdAs is Parent of FeAs superconductors structured and crystallizes in the tetragonal P4/nmm space group. Ba(1) is bonded in a 4-coordinate geometry to four equivalent As(1) and four equivalent F(1) atoms. Cd(1) is bonded to four equivalent As(1) atoms to form a mixture of corner and edge-sharing CdAs4 tetrahedra. As(1) is bonded in a 8-coordinate geometry to four equivalent Ba(1) and four equivalent Cd(1) atoms. F(1) is bonded to four equivalent Ba(1) atoms to form a mixture of corner and edge-sharing FBa4 tetrahedra.
