K La Sn Os
KLaOsSn crystallizes in the trigonal R3m space group. K(1) is bonded in a distorted single-bond geometry to one Os(1) and three equivalent Sn(1) atoms. The K(1)-Os(1) bond length is 2.08 Å. All K(1)-Sn(1) bond lengths are 3.00 Å. La(1) is bonded to three equivalent Os(1) and one Sn(1) atom to form distorted LaSnOs3 trigonal pyramids that share  a cornercorner with one Os(1)KLa3Sn trigonal bipyramid, corners with three equivalent Sn(1)K3LaOs trigonal bipyramids, and corners with six equivalent La(1)SnOs3 trigonal pyramids. All La(1)-Os(1) bond lengths are 3.00 Å. The La(1)-Sn(1) bond length is 2.08 Å. Os(1) is bonded to one K(1), three equivalent La(1), and one Sn(1) atom to form distorted OsKLa3Sn trigonal bipyramids that share corners with six equivalent Os(1)KLa3Sn trigonal bipyramids,  a cornercorner with one La(1)SnOs3 trigonal pyramid, and edges with three equivalent Sn(1)K3LaOs trigonal bipyramids. The Os(1)-Sn(1) bond length is 2.08 Å. Sn(1) is bonded to three equivalent K(1), one La(1), and one Os(1) atom to form distorted SnK3LaOs trigonal bipyramids that share corners with six equivalent Sn(1)K3LaOs trigonal bipyramids, corners with three equivalent La(1)SnOs3 trigonal pyramids, and edges with three equivalent Os(1)KLa3Sn trigonal bipyramids.
