The structure described by SrCdBi2 is Parent of FeAs superconductors-derived structured and crystallizes in the tetragonal I4/mmm space group. Sr(1) is bonded in a 8-coordinate geometry to four equivalent Bi(1) and four equivalent Bi(2) atoms. Cd(1) is bonded to four equivalent Bi(1) atoms to form a mixture of distorted edge and corner-sharing CdBi4 tetrahedra. There are two inequivalent Bi sites. In the first Bi site, Bi(1) is bonded in a 8-coordinate geometry to four equivalent Sr(1) and four equivalent Cd(1) atoms. In the second Bi site, Bi(2) is bonded in a 8-coordinate geometry to four equivalent Sr(1) and four equivalent Bi(2) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
