Gd2AgZn crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two Gd2AgZn clusters. There are two inequivalent Gd sites. In the first Gd site, Gd(1) is bonded in a distorted single-bond geometry to one Ag(1) and one Zn(1) atom. The Gd(1)-Ag(1) bond length is 1.17 Å. The Gd(1)-Zn(1) bond length is 2.00 Å. In the second Gd site, Gd(2) is bonded in a single-bond geometry to one Ag(1) atom. The Gd(2)-Ag(1) bond length is 1.17 Å. Ag(1) is bonded in an L-shaped geometry to one Gd(1) and one Gd(2) atom. Zn(1) is bonded in a single-bond geometry to one Gd(1) atom.
