K Na Ga Ga
KNaGa2 crystallizes in the trigonal R3m space group. K(1) is bonded in a distorted single-bond geometry to one Ga(2) and three equivalent Ga(1) atoms. The K(1)-Ga(2) bond length is 2.04 Å. All K(1)-Ga(1) bond lengths are 3.01 Å. Na(1) is bonded in a distorted single-bond geometry to one Ga(1) atom. The Na(1)-Ga(1) bond length is 2.04 Å. There are two inequivalent Ga sites. In the first Ga site, Ga(1) is bonded to three equivalent K(1), one Na(1), and one Ga(2) atom to form distorted corner-sharing GaK3NaGa trigonal bipyramids. The Ga(1)-Ga(2) bond length is 2.04 Å. In the second Ga site, Ga(2) is bonded in a distorted single-bond geometry to one K(1) and one Ga(1) atom.
