The material structure described by Gd2(Zn2Ge)3 crystallizes in the hexagonal P-62m space group. Gd(1) is bonded in a 15-coordinate geometry to three equivalent Zn(2), six equivalent Zn(1), and six equivalent Ge(1) atoms. There are two inequivalent Zn sites. In the first Zn site, Zn(1) is bonded in a 3-coordinate geometry to four equivalent Gd(1) and three equivalent Ge(1) atoms. In the second Zn site, Zn(2) is bonded in a distorted water-like geometry to two equivalent Gd(1) and two equivalent Ge(1) atoms. Ge(1) is bonded in a 9-coordinate geometry to four equivalent Gd(1), two equivalent Zn(2), and three equivalent Zn(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
