The material structure described by SrFe2AsP crystallizes in the tetragonal I4mm space group. Sr(1) is bonded in a 8-coordinate geometry to four equivalent As(1) and four equivalent P(1) atoms. Fe(1) is bonded to two equivalent As(1) and two equivalent P(1) atoms to form a mixture of distorted edge and corner-sharing FeAs2P2 tetrahedra. As(1) is bonded in a 8-coordinate geometry to four equivalent Sr(1) and four equivalent Fe(1) atoms. P(1) is bonded in a 8-coordinate geometry to four equivalent Sr(1) and four equivalent Fe(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
