Y Y Sn Sn
SnY is alpha carbon monoxide-like structured and crystallizes in the triclinic P-1 space group. The structure is zero-dimensional and consists of two tin;yttrium molecules. Y(1) is bonded in a single-bond geometry to one Sn(1) atom. The Y(1)-Sn(1) bond length is 0.28 Å. Sn(1) is bonded in a single-bond geometry to one Y(1) atom.
