The crystal structure described by BaAgTeF 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 Te(1) and four equivalent F(1) atoms. Ag(1) is bonded to four equivalent Te(1) atoms to form a mixture of distorted edge and corner-sharing AgTe4 tetrahedra. Te(1) is bonded in a 8-coordinate geometry to four equivalent Ba(1) and four equivalent Ag(1) atoms. F(1) is bonded to four equivalent Ba(1) atoms to form a mixture of edge and corner-sharing FBa4 tetrahedra. is represented by the Crystallographic Information File (CIF) [CIF]
