The material structure described by SrFZnAs is Parent of FeAs superconductors structured and crystallizes in the tetragonal P4/nmm space group. Sr(1) is bonded in a 4-coordinate geometry to four equivalent As(1) and four equivalent F(1) atoms. Zn(1) is bonded to four equivalent As(1) atoms to form a mixture of edge and corner-sharing ZnAs4 tetrahedra. As(1) is bonded in a 8-coordinate geometry to four equivalent Sr(1) and four equivalent Zn(1) atoms. F(1) is bonded to four equivalent Sr(1) atoms to form a mixture of edge and corner-sharing FSr4 tetrahedra. is represented by the CIF card [CIF]
