Materials Data on SrCuTeF by Materials Project
SrCuTeF 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 3.44 Å. All Sr–F bond lengths are 2.53 Å. Cu1+ is bonded to four equivalent Te2- atoms to form CuTe4 tetrahedra that share corners with four equivalent CuTe4 tetrahedra, corners with twelve equivalent FSr4Te4 tetrahedra, edges with two equivalent FSr4Te4 tetrahedra, and edges with four equivalent CuTe4 tetrahedra. All Cu–Te bond lengths are 2.67 Å. Te2- is bonded in a 12-coordinate geometry to four equivalent Sr2+, four equivalent Cu1+, and four equivalent F1- atoms. All Te–F bond lengths are 3.69 Å. F1- is bonded to four equivalent Sr2+ and four equivalent Te2- atoms to form FSr4Te4 tetrahedra that share corners with twelve equivalent CuTe4 tetrahedra, edges with two equivalent CuTe4 tetrahedra, edges with four equivalent FSr4Te4 tetrahedra, and faces with four equivalent FSr4Te4 tetrahedra.
