Materials Data on SrAgTeF by Materials Project
SrFAgTe is Parent of FeAs superconductors structured and crystallizes in the tetragonal P4/nmm space group. The structure is three-dimensional. Sr2+ is bonded in a 4-coordinate geometry to four equivalent Te2- and four equivalent F1- atoms. All Sr–Te bond lengths are 3.50 Å. All Sr–F bond lengths are 2.57 Å. Ag1+ is bonded in a 4-coordinate geometry to four equivalent Ag1+ and four equivalent Te2- atoms. All Ag–Ag bond lengths are 3.11 Å. All Ag–Te bond lengths are 2.92 Å. Te2- is bonded in a 12-coordinate geometry to four equivalent Sr2+, four equivalent Ag1+, and four equivalent F1- atoms. All Te–F bond lengths are 3.67 Å. F1- is bonded to four equivalent Sr2+ and four equivalent Te2- atoms to form a mixture of face and edge-sharing FSr4Te4 tetrahedra.
