The compound described by SrCd11 crystallizes in the tetragonal I4_1/amd space group. Sr(1) is bonded in a 18-coordinate geometry to two equivalent Cd(3) and sixteen equivalent Cd(1) atoms. There are three inequivalent Cd sites. In the first Cd site, Cd(3) is bonded in a 14-coordinate geometry to two equivalent Sr(1), four equivalent Cd(2), and eight equivalent Cd(1) atoms. In the second Cd site, Cd(1) is bonded in a 12-coordinate geometry to two equivalent Sr(1), one Cd(3), two equivalent Cd(2), and seven equivalent Cd(1) atoms. In the third Cd site, Cd(2) is bonded in a distorted q6 geometry to two equivalent Cd(3) and eight equivalent Cd(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
