The crystal structure described by Zr3Ge crystallizes in the tetragonal P4_2/n space group. There are three inequivalent Zr sites. In the first Zr site, Zr(1) is bonded in a distorted bent 150 degrees geometry to two equivalent Ge(1) atoms. In the second Zr site, Zr(2) is bonded in a distorted see-saw-like geometry to four equivalent Ge(1) atoms. In the third Zr site, Zr(3) is bonded in a 3-coordinate geometry to three equivalent Ge(1) atoms. Ge(1) is bonded in a 9-coordinate geometry to two equivalent Zr(1), three equivalent Zr(3), and four equivalent Zr(2) atoms. is represented by the CIF card [CIF]
