The material structure described by Sr4Zn11 is Magnesium tetraboride-like structured and crystallizes in the tetragonal I4_1/amd space group. Sr(1) is bonded in a 8-coordinate geometry to two equivalent Zn(3) and six equivalent Zn(1) atoms. There are three inequivalent Zn sites. In the first Zn site, Zn(1) is bonded in a 7-coordinate geometry to three equivalent Sr(1), one Zn(2), one Zn(3), and two equivalent Zn(1) atoms. In the second Zn site, Zn(2) is bonded in a 8-coordinate geometry to eight equivalent Zn(1) atoms. In the third Zn site, Zn(3) is bonded in a 8-coordinate geometry to four equivalent Sr(1) and four equivalent Zn(1) atoms. is represented by the CIF card [CIF]
