KFeAs2 crystallizes in the tetragonal I-4m2 space group. K(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 distorted corner-sharing FeAs4 tetrahedra. As(1) is bonded in a distorted bent 120 degrees geometry to four equivalent K(1) and two equivalent Fe(1) atoms.
