Cs(FeSb)2 is Parent of FeAs superconductors-derived structured and crystallizes in the tetragonal I4/mmm space group. Cs(1) is bonded to four equivalent Cs(1) and eight equivalent Sb(1) atoms to form a mixture of distorted face and corner-sharing CsCs4Sb8 cuboctahedra. Fe(1) is bonded in a 8-coordinate geometry to four equivalent Fe(1) and four equivalent Sb(1) atoms. Sb(1) is bonded in a 8-coordinate geometry to four equivalent Cs(1) and four equivalent Fe(1) atoms.
