SrZn5 crystallizes in the orthorhombic Pnma space group. Sr(1) is bonded in a 13-coordinate geometry to three equivalent Zn(1), three equivalent Zn(2), four equivalent Zn(3), and eight equivalent Zn(4) atoms. There are four inequivalent Zn sites. In the first Zn site, Zn(1) is bonded in a 8-coordinate geometry to three equivalent Sr(1), one Zn(2), and four equivalent Zn(4) atoms. In the second Zn site, Zn(2) is bonded in a 11-coordinate geometry to three equivalent Sr(1), one Zn(1), three equivalent Zn(3), and four equivalent Zn(4) atoms. In the third Zn site, Zn(3) is bonded in a 11-coordinate geometry to four equivalent Sr(1), three equivalent Zn(2), and four equivalent Zn(4) atoms. In the fourth Zn site, Zn(4) is bonded in a 12-coordinate geometry to four equivalent Sr(1), two equivalent Zn(1), two equivalent Zn(2), two equivalent Zn(3), and two equivalent Zn(4) atoms.
