Y Co Sn Sn
YCoSn2 crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two YCoSn2 clusters. Y(1) is bonded in a 2-coordinate geometry to one Co(1) and one Sn(1) atom. The Y(1)-Co(1) bond length is 1.82 Å. The Y(1)-Sn(1) bond length is 2.50 Å. Co(1) is bonded in a 2-coordinate geometry to one Y(1) and one Sn(2) atom. The Co(1)-Sn(2) bond length is 1.61 Å. There are two inequivalent Sn sites. In the first Sn site, Sn(1) is bonded in a distorted single-bond geometry to one Y(1) atom. In the second Sn site, Sn(2) is bonded in a 1-coordinate geometry to one Co(1) atom.
