KGaY crystallizes in the trigonal R3m space group. K(1) is bonded in a distorted single-bond geometry to one Y(1) and three equivalent Ga(1) atoms. The K(1)-Y(1) bond length is 1.11 Å. All K(1)-Ga(1) bond lengths are 3.32 Å. Y(1) is bonded in a linear geometry to one K(1) and one Ga(1) atom. The Y(1)-Ga(1) bond length is 2.22 Å. Ga(1) is bonded to three equivalent K(1) and one Y(1) atom to form corner-sharing GaK3Y tetrahedra.
