K Ga Ag
KAgGa crystallizes in the trigonal R3m space group. K(1) is bonded in a distorted hexagonal planar geometry to three equivalent Ag(1) and three equivalent Ga(1) atoms. All K(1)-Ag(1) bond lengths are 3.10 Å. All K(1)-Ga(1) bond lengths are 3.04 Å. Ag(1) is bonded to three equivalent K(1) and one Ga(1) atom to form AgK3Ga tetrahedra that share corners with three equivalent Ga(1)K3Ag tetrahedra, corners with six equivalent Ag(1)K3Ga tetrahedra, and edges with three equivalent Ga(1)K3Ag tetrahedra. The Ag(1)-Ga(1) bond length is 2.46 Å. Ga(1) is bonded to three equivalent K(1) and one Ag(1) atom to form GaK3Ag tetrahedra that share corners with three equivalent Ag(1)K3Ga tetrahedra, corners with six equivalent Ga(1)K3Ag tetrahedra, and edges with three equivalent Ag(1)K3Ga tetrahedra.
