La Y Sn W
LaYWSn crystallizes in the trigonal R3m space group. La(1) is bonded to three equivalent W(1) and one Sn(1) atom to form distorted LaSnW3 trigonal pyramids that share  a cornercorner with one W(1)La3YSn trigonal bipyramid, corners with three equivalent Sn(1)LaY3W trigonal bipyramids, and corners with six equivalent La(1)SnW3 trigonal pyramids. All La(1)-W(1) bond lengths are 2.99 Å. The La(1)-Sn(1) bond length is 2.20 Å. Y(1) is bonded in a distorted single-bond geometry to one W(1) and three equivalent Sn(1) atoms. The Y(1)-W(1) bond length is 2.20 Å. All Y(1)-Sn(1) bond lengths are 2.99 Å. W(1) is bonded to three equivalent La(1), one Y(1), and one Sn(1) atom to form distorted WLa3YSn trigonal bipyramids that share corners with six equivalent W(1)La3YSn trigonal bipyramids,  a cornercorner with one La(1)SnW3 trigonal pyramid, and edges with three equivalent Sn(1)LaY3W trigonal bipyramids. The W(1)-Sn(1) bond length is 2.20 Å. Sn(1) is bonded to one La(1), three equivalent Y(1), and one W(1) atom to form distorted SnLaY3W trigonal bipyramids that share corners with six equivalent Sn(1)LaY3W trigonal bipyramids, corners with three equivalent La(1)SnW3 trigonal pyramids, and edges with three equivalent W(1)La3YSn trigonal bipyramids.
