SrFe2As2 crystallizes in the tetragonal I4/mmm space group. Sr(1) is bonded in a distorted body-centered cubic geometry to eight equivalent As(1) atoms. Fe(1) is bonded to four equivalent As(1) atoms to form a mixture of corner and edge-sharing FeAs4 tetrahedra. As(1) is bonded in a 8-coordinate geometry to four equivalent Sr(1) and four equivalent Fe(1) atoms.
