K La Al Au
KLaAuAl crystallizes in the trigonal R3m space group. K(1) is bonded to one La(1), three equivalent Au(1), and one Al(1) atom to form KLaAlAu3 trigonal bipyramids that share corners with six equivalent K(1)LaAlAu3 trigonal bipyramids and  a cornercorner with one Au(1)K3La trigonal pyramid. The K(1)-La(1) bond length is 2.15 Å. All K(1)-Au(1) bond lengths are 2.99 Å. The K(1)-Al(1) bond length is 2.15 Å. La(1) is bonded in a 2-coordinate geometry to one K(1) and one Au(1) atom. The La(1)-Au(1) bond length is 2.15 Å. Au(1) is bonded to three equivalent K(1) and one La(1) atom to form distorted AuK3La trigonal pyramids that share  a cornercorner with one K(1)LaAlAu3 trigonal bipyramid and corners with six equivalent Au(1)K3La trigonal pyramids. Al(1) is bonded in a distorted single-bond geometry to one K(1) atom.
