RbFe2As2 is Parent of FeAs superconductors-derived structured and crystallizes in the tetragonal I4/mmm space group. Rb(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 distorted corner and edge-sharing FeAs4 tetrahedra. As(1) is bonded in a 8-coordinate geometry to four equivalent Rb(1) and four equivalent Fe(1) atoms.
