K3YSn crystallizes in the trigonal R3m space group. K(1) is bonded in a 3-coordinate geometry to two equivalent Y(1) and one Sn(1) atom. There is one shorter (2.74 Å) and one longer (4.06 Å) K(1)-Y(1) bond length. The K(1)-Sn(1) bond length is 3.88 Å. Y(1) is bonded to six equivalent K(1) atoms to form distorted corner-sharing YK6 octahedra. The corner-sharing octahedra are not tilted. Sn(1) is bonded in a 3-coordinate geometry to three equivalent K(1) atoms.
