Ba Y Sn Rh
BaYRhSn crystallizes in the trigonal R3m space group. Ba(1) is bonded in a distorted single-bond geometry to one Rh(1) and three equivalent Sn(1) atoms. The Ba(1)-Rh(1) bond length is 2.13 Å. All Ba(1)-Sn(1) bond lengths are 2.99 Å. Y(1) is bonded to three equivalent Rh(1) and one Sn(1) atom to form distorted YSnRh3 trigonal pyramids that share  a cornercorner with one Rh(1)BaY3Sn trigonal bipyramid, corners with three equivalent Sn(1)Ba3YRh trigonal bipyramids, and corners with six equivalent Y(1)SnRh3 trigonal pyramids. All Y(1)-Rh(1) bond lengths are 2.99 Å. The Y(1)-Sn(1) bond length is 2.13 Å. Rh(1) is bonded to one Ba(1), three equivalent Y(1), and one Sn(1) atom to form distorted RhBaY3Sn trigonal bipyramids that share corners with six equivalent Rh(1)BaY3Sn trigonal bipyramids,  a cornercorner with one Y(1)SnRh3 trigonal pyramid, and edges with three equivalent Sn(1)Ba3YRh trigonal bipyramids. The Rh(1)-Sn(1) bond length is 2.13 Å. Sn(1) is bonded to three equivalent Ba(1), one Y(1), and one Rh(1) atom to form distorted SnBa3YRh trigonal bipyramids that share corners with six equivalent Sn(1)Ba3YRh trigonal bipyramids, corners with three equivalent Y(1)SnRh3 trigonal pyramids, and edges with three equivalent Rh(1)BaY3Sn trigonal bipyramids.
