K Li Ag Sn
KLiAgSn crystallizes in the trigonal R3m space group. K(1) is bonded to one Li(1), one Ag(1), and three equivalent Sn(1) atoms to form distorted KLiAgSn3 trigonal bipyramids that share corners with six equivalent K(1)LiAgSn3 trigonal bipyramids,  a cornercorner with one Sn(1)K3Ag trigonal pyramid, and corners with three equivalent Li(1)KAg3 trigonal pyramids. The K(1)-Li(1) bond length is 2.10 Å. The K(1)-Ag(1) bond length is 2.10 Å. All K(1)-Sn(1) bond lengths are 3.00 Å. Li(1) is bonded to one K(1) and three equivalent Ag(1) atoms to form LiKAg3 trigonal pyramids that share corners with three equivalent K(1)LiAgSn3 trigonal bipyramids, corners with six equivalent Li(1)KAg3 trigonal pyramids, and edges with three equivalent Sn(1)K3Ag trigonal pyramids. All Li(1)-Ag(1) bond lengths are 3.00 Å. Ag(1) is bonded in a distorted single-bond geometry to one K(1), three equivalent Li(1), and one Sn(1) atom. The Ag(1)-Sn(1) bond length is 2.10 Å. Sn(1) is bonded to three equivalent K(1) and one Ag(1) atom to form SnK3Ag trigonal pyramids that share  a cornercorner with one K(1)LiAgSn3 trigonal bipyramid, corners with six equivalent Sn(1)K3Ag trigonal pyramids, and edges with three equivalent Li(1)KAg3 trigonal pyramids.
