K2LiGa is Cyanogen Chloride-like structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two K2LiGa clusters. There are two inequivalent K sites. In the first K site, K(1) is bonded in a single-bond geometry to one Ga(1) atom. The K(1)-Ga(1) bond length is 1.61 Å. In the second K site, K(2) is bonded in a linear geometry to one Li(1) and one Ga(1) atom. The K(2)-Li(1) bond length is 0.81 Å. The K(2)-Ga(1) bond length is 1.61 Å. Li(1) is bonded in a single-bond geometry to one K(2) atom. Ga(1) is bonded in a linear geometry to one K(1) and one K(2) atom.
