K Li In Cu
KLiCuIn crystallizes in the trigonal R3m space group. K(1) is bonded to one Li(1), three equivalent Cu(1), and one In(1) atom to form distorted KLiInCu3 trigonal bipyramids that share corners with six equivalent K(1)LiInCu3 trigonal bipyramids,  a cornercorner with one Cu(1)K3In trigonal pyramid, corners with three equivalent Li(1)KIn3 trigonal pyramids, and edges with three equivalent In(1)KLi3Cu trigonal bipyramids. The K(1)-Li(1) bond length is 2.21 Å. All K(1)-Cu(1) bond lengths are 2.99 Å. The K(1)-In(1) bond length is 2.21 Å. Li(1) is bonded to one K(1) and three equivalent In(1) atoms to form LiKIn3 trigonal pyramids that share  a cornercorner with one In(1)KLi3Cu trigonal bipyramid, corners with three equivalent K(1)LiInCu3 trigonal bipyramids, corners with six equivalent Li(1)KIn3 trigonal pyramids, and edges with three equivalent Cu(1)K3In trigonal pyramids. All Li(1)-In(1) bond lengths are 2.99 Å.
