KGa2 crystallizes in the triclinic P-1 space group. The structure is zero-dimensional and consists of two KGa2 clusters. K(1) is bonded in a 1-coordinate geometry to one Ga(2) atom. The K(1)-Ga(2) bond length is 2.23 Å. There are two inequivalent Ga sites. In the first Ga site, Ga(1) is bonded in a distorted single-bond geometry to one Ga(2) atom. The Ga(1)-Ga(2) bond length is 1.15 Å. In the second Ga site, Ga(2) is bonded in a water-like geometry to one K(1) and one Ga(1) atom.
