KCoSn2 crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one KCoSn2 cluster. K(1) is bonded in a single-bond geometry to one Co(1), one Sn(1), and one Sn(2) atom. The K(1)-Co(1) bond length is 1.66 Å. The K(1)-Sn(1) bond length is 0.21 Å. The K(1)-Sn(2) bond length is 2.97 Å. Co(1) is bonded in a 1-coordinate geometry to one K(1) atom. There are two inequivalent Sn sites. In the first Sn site, Sn(1) is bonded in a single-bond geometry to one K(1) atom. In the second Sn site, Sn(2) is bonded in a distorted single-bond geometry to one K(1) atom.
