Ac Ac Gd Gd
GdAc crystallizes in the monoclinic P2 space group. The structure is zero-dimensional and consists of one GdAc cluster. Ac(1) is bonded in a distorted single-bond geometry to one Ac(1) and one Gd(1) atom. The Ac(1)-Ac(1) bond length is 0.42 Å. The Ac(1)-Gd(1) bond length is 0.88 Å. Gd(1) is bonded in a single-bond geometry to one Ac(1) atom.
