AcGdEu2 crystallizes in the trigonal R3m space group. Ac(1) is bonded in a distorted linear geometry to three equivalent Gd(1), one Eu(1), and one Eu(2) atom. All Ac(1)-Gd(1) bond lengths are 3.54 Å. The Ac(1)-Eu(1) bond length is 2.30 Å. The Ac(1)-Eu(2) bond length is 2.30 Å. Gd(1) is bonded to three equivalent Ac(1) and one Eu(1) atom to form distorted corner-sharing GdAc3Eu trigonal pyramids. The Gd(1)-Eu(1) bond length is 2.30 Å. There are two inequivalent Eu sites. In the first Eu site, Eu(1) is bonded in a distorted linear geometry to one Ac(1) and one Gd(1) atom. In the second Eu site, Eu(2) is bonded in a single-bond geometry to one Ac(1) atom.
