K Sn W W
KW2Sn crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one KW2Sn cluster. K(1) is bonded in a single-bond geometry to one W(1) and one Sn(1) atom. The K(1)-W(1) bond length is 2.99 Å. The K(1)-Sn(1) bond length is 0.52 Å. There are two inequivalent W sites. In the first W site, W(1) is bonded in a 2-coordinate geometry to one K(1) and one W(2) atom. The W(1)-W(2) bond length is 0.40 Å. In the second W site, W(2) is bonded in a distorted single-bond geometry to one W(1) atom. Sn(1) is bonded in a single-bond geometry to one K(1) atom.
