Ba Ga Ga Fe
BaFe(Ga)2 crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two digallane molecules and two BaFe clusters. In each BaFe cluster, Ba(1) is bonded in a single-bond geometry to one Fe(1) atom. The Ba(1)-Fe(1) bond length is 1.03 Å. Fe(1) is bonded in a single-bond geometry to one Ba(1) atom.
