Zr Co Sn Sn
ZrCoSn2 is Cyanogen Chloride-like structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two ZrCoSn2 clusters. Zr(1) is bonded in a distorted linear geometry to one Co(1) and one Sn(1) atom. The Zr(1)-Co(1) bond length is 0.90 Å. The Zr(1)-Sn(1) bond length is 1.81 Å. Co(1) is bonded in a linear geometry to one Zr(1) and one Sn(2) atom. The Co(1)-Sn(2) bond length is 0.91 Å. There are two inequivalent Sn sites. In the first Sn site, Sn(1) is bonded in a single-bond geometry to one Zr(1) atom. In the second Sn site, Sn(2) is bonded in a single-bond geometry to one Co(1) atom.
