The material described by Sr4Cd11 crystallizes in the tetragonal I4_1/amd space group. Sr(1) is bonded in a 7-coordinate geometry to one Cd(1), one Cd(2), and six equivalent Cd(3) atoms. There are three inequivalent Cd sites. In the first Cd site, Cd(1) is bonded in a 4-coordinate geometry to four equivalent Sr(1) atoms. In the second Cd site, Cd(2) is bonded in a distorted hexagonal planar geometry to two equivalent Sr(1) and four equivalent Cd(3) atoms. In the third Cd site, Cd(3) is bonded in a 9-coordinate geometry to three equivalent Sr(1), one Cd(2), and five equivalent Cd(3) atoms. is represented by the CIF file [CIF]
